== Recommendations ==


The recommended installation method is with a boot media with the Anaconda installer as detailed in the [http://docs.fedoraproject.org/install-guide/ Installation Guide].
{{admon/warning| Upgrading using the yum method described here is not officially supported by FedoraQA. Please instead use the official upgrade tool, [[FedUp]]. }}


[[PreUpgrade]] is a slightly different upgrade method where the all packages are downloaded before the system is rebooted into the Anaconda installer.
This page contains information explaining how to upgrade Fedora using {{command|yum}}.

{{admon/caution|Use caution|Although upgrades with yum have been tested and work, live upgrades are not recommended by the Fedora Project. If you are not prepared to resolve issues on your own if things break, you should probably use the recommended installation methods instead.}}
When upgrading with yum you don't get any help from [[FedUp]], but with a typical system it might be able to upgrade systems remotely over ssh and with limited downtime. (You will still need to reboot to get the new kernel and system libraries/services running).  


When upgrading with yum you don't get any help from Anaconda, but if you are lucky you might be able to upgrade systems remotely over ssh and with limited downtime. (You will still need to reboot to get the new kernel and system libraries/services running) Rebooting after such an upgrade is always very exciting.
Although upgrades with yum do work, they are not explicitly tested as part of the release process by the [[QA|Fedora QA]] and are not documented in the [http://docs.fedoraproject.org/en-US/Fedora/{{FedoraVersion}}/html/Installation_Guide/index.html Fedora installation guide].

=== 4. Do the upgrade ===


<pre>
If you have 3rd party repositories configured, you may need to adjust them for the new Fedora version. If you switch from one Fedora release to another there is often nothing that needs to be done.  If you switch to Rawhide from a standard Fedora release (or vice versa) then most of the time you will need to install the Rawhide release RPMs from the 3rd party repository as well (or the standard ones, if switching back).
yum clean all
</pre>


=== 4. Switch repositories ===
Note that the upgrade is likely to fail if there are outdated dependencies from packages not backed by a yum repository or backed by a repository which isn't ready for the new version.
 
Update the packages that decide which yum repositories to use.
 
<pre>
rpm -Uhv ftp://download.fedora.redhat.com/pub/fedora/linux/releases/<ReleaseNumber>/Fedora/<Arch>/os/Packages/fedora-release-*.noarch.rpm
</pre>


(The architecture doesn't matter for this <code>noarch</code> package.)
It is a good idea to do the upgrade outside the graphical environment. Log out of your graphical desktop and then


'''Note:''' Some users have reported that attempting to download through rpm returns a 550 response and "transfer failed" messages.  If this is the case, you can download the rpms and install locally.  Consider:

rpm -Uvh fedora-release-*.noarch.rpm
</pre>


Make sure the new repo files isn't placed as <code>.rpmnew</code> files, perhaps by
A small script named fedora-upgrade is available which aims to automate the process outlined below. To run it, do the following


<pre>
<pre>$ sudo yum install fedora-upgrade
mv /etc/yum.repos.d/fedora-updates.repo.rpmnew /etc/yum.repos.d/fedora-updates.repo
$ sudo fedora-upgrade
mv /etc/yum.repos.d/fedora.repo.rpmnew /etc/yum.repos.d/fedora.repo

If using selinux make sure it is in permissive mode - neither disabled nor enforcing.
Alternatively, follow the manual steps:

==== Update yum to latest version available in your Fedora version ====
 
{{admon/tip|Update all packages at once| Although you can try to update the update machinery first with <code>yum update rpm\* yum\*</code> or with <code>glibc</code>, in both cases dependencies might expand it to an almost full upgrade anyway, and simply doing a full upgrade might be more safe (but your mileage may vary). (In particular, do not upgrade rpm and yum separately if upgrading to a system with a different version of python e.g. 2.4 to 2.5.)
}}
 
Upgrade all packages with


<pre>
<pre>
yum upgrade
# yum update yum
</pre>
</pre>


<code>yum</code> might complain about conflicts or requirements. That is probably because you have used non-standard repositories or installed non-standard packages manually. Try to guess which packages cause the problem (or at least is a part of the dependency chain) - uninstall them and try again. Remember to install the packages again if they are essential.
==== Install the new fedora gpg key for the version you are updating to ====


Ensure that all (new) essential packages from the new version are installed with
Keys you may find and verify  at


<pre>
https://fedoraproject.org/keys
yum groupupdate Base
</pre>


You might want to update other groups too, see
or see a version specific update instructions at the bottom.


<pre>
==== Clean the cache ====
yum grouplist
</pre>


For example
Then remove all traces of the version you are leaving from the yum cache in <code>/var/cache/yum</code>.


<pre>
<pre>
yum groupupdate "GNOME Desktop Environment" \
# yum clean all
"Development Tools" "Server Configuration Tools" \
"Hardware Support" "Sound and Video" \
"Graphical Internet" "Fonts" \
"Games and Entertainment" "Printing Software" \
"Administration Tools" "Office/Productivity" "System Tools"
</pre>
</pre>


=== 6. Preparing for reboot ===
==== Upgrade all packages ====


Before booting you should usually install the bootloader from your new grub by running
{{admon/warning|Once a live upgrade is started, do not stop the upgrade by rebooting, killing the process, or by any other method until it is complete. Interrupting an upgrade will cause the affected system to be in a mixed state -- partially the old release and partially the new release.  In this state, the system will not be reliable and will not operate as expected.  You can try running yum distro-sync and package-cleanup --problems to try and fix the problems. }}
<pre>
/sbin/grub-install BOOTDEVICE
</pre>
- where BOOTDEVICE is usually <code>/dev/sda</code> (If you get an error '/dev/sda does not have any corresponding BIOS drive' from that, then try <tt>/sbin/grub-install --recheck /dev/sda</tt>.)


Also, the order of init scripts could have changed from the previous version. A command to reset the order is:
<pre>
<pre>
cd /etc/rc.d/init.d; for f in *; do /sbin/chkconfig $f resetpriorities; done
# yum --releasever=<release_number_you_want_to_sync_to> distro-sync
</pre>
</pre>


Again, run <code>package-cleanup --orphans</code> to find packages that haven't been upgraded.
{{admon/warning|If you experience any dependency problems, you have to solve them manually. Most often it is enough to remove several problematic package(s). Be very careful when doing so however.

== Version specific notes ==
 
=== From pre-release ===


If you are upgrading to a final release from an alpha, beta, preview, or other [[Releases/Rawhide|Rawhide]] release, please see [[Upgrading from pre-release to final]].
'''Note:''' While it is recommended to upgrade to intermediate releases if upgrading from an older release (for example upgrading from Fedora 19 to 20, then 20 to 21), depending on what version you are upgrading from, this step may fail with an error about GPG keys being in the wrong format.  To overcome this, you can add the "--nogpgcheck" switch to the above yum distro-sync command.


{{Anchor|12-13}}
=== 5. Make sure Fedora is upgraded ===
=== Fedora 12 -> Fedora 13 ===
* The release files can currently be found on ftp://download.fedora.redhat.com/pub/fedora/linux/releases/development/13/i386/os/Packages/fedora-release-*.noarch.rpm
* Testing shows that upgrading within X will cause X to hang when installing <code>bitmap-fonts-compat</code>, but it can be done anyway by making sure that <code>bitmap-fonts-compat</code> is the last package to update ... YMMV.
* /sbin/shutdown and /sbin/init do not function properly after the upgrade.  To reboot your system, you must physically press the power button for 5 seconds, or have another method to initiate a powercycle (e.g. IPMI controller), for example: <code>echo 1 > /proc/sys/kernel/sysrq</code>. ([[rhbug:577709]] Note: It is reported there that <code>kill -9 1</code> makes shutdown and init work. Please report any experience there.).
* Intel video no longer works without Kernel Mode Setting (KMS).  You must remove 'nomodeset' from your /etc/grub.conf kernel command line, if present.
* nVidia video no longer works without kernel mode Setting (KMS).  You must remove 'nomodeset' from your /etc/grub.conf kernel command line, if present.


Distro-sync will usually take care of upgrades for the third party repositories you have enabled as well.  Confirm with <pre> yum repolist </pre>  after the upgrade process is over.  <code>yum</code> might complain about conflicts or requirements. That is probably because you have used non-standard repositories or installed non-standard packages manually. Try to guess which packages cause the problem (or at least is a part of the dependency chain) - uninstall them and try again. Remember to install the packages again if they are essential. 


{{Anchor|11-12}}
Ensure that all (new) essential packages from the new version are installed with
 
=== Fedora 11 -> Fedora 12 ===
 
* All Fedora 12 RPM packages use XZ/LZMA compression, which is only supported by the [https://admin.fedoraproject.org/updates/F11/FEDORA-2009-7986 rpm-4.7.1-1 update] (or later) for Fedora 11. Before upgrading from Fedora 11, run <code>yum update rpm</code>.
* It is not possible to update directly from Fedora 10 or earlier with yum. To upgrade from Fedora 10, first update to Fedora 11, and then upgrade from Fedora 11 to Fedora 12. If you are using a release before Fedora 10, use one of the official upgrade methods or backup your data, perform a fresh installation, and restore from backup.
* Upgrades from Fedora 11 might currently fail with missing dependencies (for example related to {{package|totem-gstreamer}} or {{package|PolicyKit-kde}}). The dependencies are ok, but Fedora 11 {{package|yum}} has problems resolving them ([[rhbug:519172|bug 519172]]).
* If your root filesystem does not mount with 'defaults' options, you will need to add the root filesystem's mount options to grub.conf with the kernel flag <code>rootflags</code> - initramfs does not pick up the options the way initrd used to.  e.g. if you mount your root with the flags <code>data=journal,relatime</code> then you would add to the end of the 'kernel' line in grub.conf: <code>rootflags=data=journal,relatime</code> .  After updating to dracut-004-4.fc12 or later, this kernel flag can be removed.
 
{{Anchor|10-11}}
 
=== Fedora 10 -> Fedora 11 ===


* It is only possible to upgrade to Fedora 11 from an updated Fedora 10. Older systems must be upgraded to Fedora 10 first. The RPM format has been changed for Fedora 11, so the older <code>rpmlib</code> must be updated first.  Otherwise the process will fail with <code>rpmlib(FileDigests)</code> dependency problems. Support for the new format has been backported to Fedora 10 in an update.
<pre>
<pre>
yum update rpm
# yum groupupdate 'Minimal Install'
</pre>
</pre>
* New <code>initrd</code> built when installing a new kernel while running Fedora 10 might fail. To solve that boot with an old kernel (to get the new userspace) and (re)install the new kernel.
* Systems with PAE support (indicated by <code>pae</code> in <code>/proc/cpuinfo</code>) should use <code>kernel-PAE.i686</code>. The new kernel must be changed/installed manually: Set <code>DEFAULTKERNEL=kernel-PAE</code> in <code>/etc/sysconfig/kernel</code> and <code>yum install kernel-PAE</code>. Refer to [http://www.codemonkey.org.uk/?p=142 Dave Jones' blog post] for details.
* The yum update step should NOT be run inside a gnome desktop session/gnome-terminal. [[rhbug:494046|Bug #494046]] could result in a unusable install when gnome-terminal segfaults during the upgrade. Update should be run in a vty, runlevel 3, or a screen session.
* fedora-release-11-1.noarch changes the yum mirrorlist URL so that it uses a  "metalink", but the version of yum currently in F10 doesn't understand this syntax, leading to yum downloads failing with this error message:
YumRepo Error: All mirror URLs are not using ftp, http[s] or file.
  Eg. </metalink>/
This is [[rhbug:498720|bug #498720]].  Workaround is to manually edit the URL in /etc/yum.repos.d/fedora.repo as described at https://www.redhat.com/archives/fedora-list/2009-June/msg00783.html
* Some packages in Fedora 10 are regarded as newer than those supplied by Fedora 11 and its updates repository. These include ntpd, ntpdate ([[rhbug:506040|bug #506040]], [[rhbug:504980|bug #504980]]), unique, unique-devel, eclipse-changelog, eclipse-svnkit and svnkit. You may wish to remove these before performing the upgrade, then reinstall them afterwards. Doing so may require <code>--nodeps</code>.
* Some i386 packages in Fedora 10 are replaced with i586, i686 or x86_64 packages in Fedora 11. These include gpm.i386, glibc-2.9-3.i386. You may wish to remove these before performing the upgrade, then reinstall them afterwards. Doing so may require <code>--nodeps</code>.
* mplayer-1.0-0.104.20090204svn.fc10 from the RPM Fusion repository has a dependency on libfaad.so.0 that the depsolve doesn't find, but rpm_check_debug does. You may wish to remove mplayer before performing the upgrade, then reinstall them afterwards. Doing so may require <code>--nodeps</code>.


{{Anchor|9-10}}
You might want to update other groups too, see
 
=== Fedora 9 -> Fedora 10 ===
 
* Check the [http://docs.fedoraproject.org/install-guide/f10/en_US/ Fedora 10 Installation Guide] and [http://docs.fedoraproject.org/release-notes/f10/en_US/ Fedora 10 Release Notes]
* <code>fedora-release</code> packages can be found at <code>rpm -Uvh ftp://download.fedora.redhat.com/pub/fedora/linux/releases/10/Fedora/i386/os/Packages/fedora-release-*.noarch.rpm</code>
* GDM starts on tty1 by default, not tty7.
* anaconda by default now refers to encrypted devices by UUID, not by device name, to better handle device name changes. An encrypted device using partition <code>/dev/sda1</code> with UUID <code>12345678-1234-1234-1234-123456789012</code> would now be called <code>/dev/mapper/luks-12345678-1234-1234-1234-123456789012</code> instead of <code>/dev/mapper/luks-sda1</code>. You may wish to make the same changes on your system on upgrade; if you do, make sure to run <code>mkinitrd</code> afterwards.
* If you use non-root encrypted devices, you will need to re-run <code>mkinitrd</code> for any older kernels that you want to still boot on the system.
* It's been reported that there are problems with Pidgin i.e.:
** <code>pidgin-2.5.2-2.fc9.i386 from installed has depsolving problems - Error: Missing Dependency: libedataserver-1.2.so.9 is needed by package pidgin-2.5.2-2.fc9.i386 (installed)</code>
** the fix was to remove Pidgin
 
{{Anchor|8-9}}
=== Fedora 8 -> Fedora 9 ===
 
* Check the [http://docs.fedoraproject.org/release-notes/f9/en_US/sn-Installer.html#Upgrade-Related-Issues Installer section in Release Notes])
* After "the incident" you should use updated fedora-release packages from <code>rpm -Uvh ftp://download.fedora.redhat.com/pub/fedora/linux/updates/9/i386.newkey/fedora-release-*.noarch.rpm</code>
* If you are running as a <code>xen</code> Host (Dom0) you should not upgrade to Fedora 9. [http://www.redhat.com/archives/fedora-xen/2008-March/msg00013.html]
* Upgrading the thunderbird package will [[rhbug:446351|fail]] . The current workaround is <code>yum remove thunderbird; yum install thunderbird</code>.
* If you are upgrading to Fedora 9 and use <code>emacs</code>, you must upgrade to the latest version of <code>emacs</code> for your prior release to ensure a clean upgrade. Fedora 8 users must have <code>emacs-22.1-10.fc8</code> or later, while Fedora 7 users must have <code>emacs-22.1-7.fc7</code>.  Bug report [[rhbug:239745|here]].
* Due to the switch from sysvinit to [http://fedoraproject.org/wiki/Features/Upstart Upstart] , it is recommended that users who do an upgrade on a live filesystem to Fedora 9 reboot soon afterwards. If you do not reboot, you may want to take careful note of any '/etc/inittab.rpmsave' or '/etc/inittab.rpmnew' files. When rebooting after an upgrade then be aware that sysvinit that was used to start the system can't be used to shut it down.
* You may find that after upgrading, you can no longer log in to GNOME. If this is the case, use ctrl-alt-F1 to access command prompt, then check the tail of .xsession-errors. If you see a comment like "(named color or font does not exist)", then you may be able to fix this using http://matthew.peach.net.nz/2008/05/18/how-to-fix-badname-named-color-or-font-does-not-exist-error/.
 
{{Anchor|7-8}}
 
=== Fedora 7 -> Fedora 8 ===
 
* New pulseaudio and flash support packages must be installed manually:


<pre>
<pre>
yum groupinstall sound-and-video gnome-desktop (if you are using Gnome)
# yum grouplist
yum groupinstall sound-and-video kde-desktop (if you are using KDE)
yum install libflashsupport paman padevchooser
</pre>
</pre>


* The Fedora 7 avahi packagage fails to uninstall; remove it manually with
For example


<pre>
<pre>
rpm -e --noscripts avahi-0.6.17-1.fc7
# yum groupupdate "GNOME Desktop" \
    "Development Tools" "Sound and Video" \
    "Games and Entertainment" "Administration Tools" \
    "Office/Productivity" "System Tools"
</pre>
</pre>


* On 64 bit machines (x86_64) you may have to remove some 32 bit libraries. For example dbus:
=== 6. Preparing for reboot ===
 
<pre>
yum erase dbus.i386
</pre>


* You may find it easier to use the yum shell to stack these commands in a single transaction:
{{Anchor|bootloader}}


Before booting you should usually install the bootloader from your new grub by running
<pre>
<pre>
yum shell
/usr/sbin/grub2-install BOOTDEVICE
> erase dbus.i386
> update
> run
</pre>
</pre>
- where BOOTDEVICE is usually <code>/dev/sda</code> (If you get an error '/dev/sda does not have any corresponding BIOS drive' from that, then try <tt>/usr/sbin/grub2-install --recheck /dev/sda</tt>).


* A lot of KDE packages are no longer multilib in F8. If you are on x86_64, you will need to erase the i386 versions of these packages by hand, like so:
It might also be necessary to update the grub config file:
 
<pre>
<pre>
yum erase kde{accessibility{,-devel},base,edu,graphics,multimedia{,-extras},network,sdk,utils{,-devel},webdev}.i386
cp --backup=numbered -a /boot/grub2/grub.cfg{,.bak} # create backup copy
/usr/sbin/grub2-mkconfig -o /boot/grub2/grub.cfg # update config file
</pre>
</pre>


* Various other packages including Beryl are no longer in F8 and not obsoleted:
Also, the order of init scripts could have changed from the previous version. A command to reset the order is:
 
<pre>
<pre>
yum erase beryl\*
cd /etc/rc.d/init.d; for f in *; do [ -x $f ] && /sbin/chkconfig $f resetpriorities; done
</pre>
</pre>


{{Anchor|6-7}}
=== 7. Cleanup your system ===
=== Fedora Core 6 -> Fedora 7 ===
Again, cleanup your system as described in section 2. Also you might want to remove some cache files that are no longer used, for example files from older Fedora releases in the following directories:


* Fedora 7 replaces the old IDE subsystem with libata. Drive device names which previously started /dev/hd.. will become /dev/sd.. after the upgrade. /dev/hda1 will usually become /dev/sda1, although there may not be a direct relationship between the old and new device names (for example hdd does not necessarily become sdd). Before you reboot be sure to change all references to /dev/hd.. in your config, especially /etc/fstab - where it however may be simpler to refer to filesystems by label (check out the programs blkid, tune2fs, and mlabel). LVM Volume names are not affected. In /boot/grub/device.map change /dev/hd.. to /dev/sd.. before running grub-install - and don't change (hd0). Changing /boot/grub/grub.conf may also be required.
* <nowiki>/var/cache/yum</nowiki>
* <nowiki>/var/cache/dnf</nowiki>
* <nowiki>/var/cache/mock</nowiki>
* <nowiki>/var/lib/mock</nowiki>


* The libata layer represents all hard disks as SCSI disks, which are limited to 15 partitions in the kernel. IDE hard disks with more than 15 partitions are not supported in Fedora 7.
== Version specific notes ==


* On a system which has been upgraded from releases prior to FC6 you may need to remove up2date and rhnlib <code>rpm -e rhnlib up2date</code>
=== From pre-release ===


* If you see the message <code>package gpm-1.20.1-84.fc6 (which is newer than gpm-1.20.1-83.fc7) is already installed</code> when performing a <code>yum update</code> uninstall and reinstall the gpm package.
If you are upgrading to a final release from an alpha, beta, preview, or other [[Releases/Rawhide|Rawhide]] release, please see [[Upgrading from pre-release to final]].


* If you had installed Suns jre it might be removed during upgrade. Be aware that <code>jre-6u1</code>/<code>jre-1.6.0_01-fcs</code> requires <code>compat-libstdc++-33</code>.
{{Anchor|Rawhide}}
=== To rawhide ===


* If you get <code>Error: Missing Dependency: python(abi) = 2.4 is needed by package libxml2-python</code> and/or <code>Error: Missing Dependency: python(abi) = 2.4 is needed by package rpm-python</code> during your <code>yum upgrade</code> ensure you have done a <code>yum clean all</code> and check that both the <code>base</code> and <code>updates</code> repositories are available from your mirror. You will need the <code>updates</code> repo for the upgrade to succeed.
{{admon/warning| Rawhide is the development branch of Fedora. It is meant to be used by developers and testers to provide feedback to the Fedora Project.}}


* Since Fedora Core 6 uses python 2.4 and Fedora 7 uses python 2.5, do not try and run <code>yum upgrade yum\* rpm\*</code> before upgrading everything else - this succeeds but leaves yum in an unusable state.
See the [[Releases/Rawhide|Rawhide]] release page for more information on Rawhide.

* After upgrading, you cannot use the DVD ISO loopback mounted as a repository directly (e.g. no <code>baseurl=file:///mnt/fc6/</code>) because the repodata files contain URLs of type <code>media://</code>  which yum can't handle. You can use the loopback-mounted DVD for the initial upgrade from FC5 -> FC6, just not thereafter.  After removing the <code>baseurl=file:///</code> option from your <code>fedora-core.repo</code> file, remember to <code>yum clean all</code>.
## Optional: it is generally advised to do a selinux autorelabel and reboot
# touch /.autorelabel
</pre>


=== Fedora Core 4 -> Fedora Core 5 ===


* Before upgrading update your kernel first.
{{Anchor|20-21}}


* Make sure you have the latest kernel ABOVE 2.6.14 and uninstall all kernel versions before it, otherwise initscripts and a few other packages will conflict and prevent the ugprade. Use something like the command below
=== Fedora 21 -> Fedora 22 ===


* Install <code>fedora-release</code> in the Fedora Core 5 version. Check our [http://fedora.redhat.com/Download/mirrors.html mirror sites] for a faster download.
# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-22-$(uname -i)
# yum update yum
# yum clean all
  # yum --releasever=22 distro-sync


* Update your system
=== Fedora 20 -> Fedora 21 ===


* After upgrading, selinux permissions may be incorrect, causing interesting failures such as metacity not starting. As suggested below, to fix this, run <code>touch /.autorelabel</code> and reboot
# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-21-$(uname -i)
# yum update yum
# yum clean all
# yum --releasever=21 distro-sync


=== Fedora Core 3 -> Fedora Core 4 ===
Fedora 21 split into different products. Execute '''one''' of those commands:


* make sure you're on the latest version of yum for FC3:
# yum install system-release-workstation
<code> yum update yum </code>
# yum install system-release-cloud
* Download fedora-release for FC4:
# yum install system-release-server
* wget http://yourmirrorhere/pub/fedora/linux/core/4/$yourarch/os/Fedora/RPMS/fedora-release-4-2.noarch.rpm
* <code>rpm -Uvh /path/to/fedora-release-4-2.noarch.rpm</code>
* yum update ( This will start the upgrade process to FC4)
* Once you have updated, run: <code>yum groupinstall "GNOME Desktop Environment"</code> (change GNOME to KDE if appropriate). That'll get you some new packages that were added in FC4 like Evince and NetworkManager.
* Some new groups were added - <code> yum grouplist </code> - check out Eclipse and Java Development in particular.


Problems:
or this one if you want to have non-productized Fedora


* Postgres database in FC4 has a newer incompatible format from the previous versions. Manual dump and restoration is required if you using this database. Look at the postgres documentation for more details on this.
# yum install system-release-nonproduct


* kernel requires kernel-utils (or vice-versa) run:
If you change your mind, you can easily switch between products.  
<pre>
yum update kernel
reboot
yum remove kernel-2.6.11\*FC3\*
yum upgrade
reboot
</pre>


* Takes a long while and hangs at:
# yum swap system-release-cloud system-release-workstation
<code> Reading repository metadata in from local files </code>
This means you have too much content in your rpmdb and it's taking a while to go through it. Check to see how many kernels you have installed: rpm -q kernel kernel-smp and remove the old ones you may also try running: rpm --rebuilddb and see if it helps. I've found that removing old kernels and rebuilding the rpmdb resolves this problem.


* x86_64 upgrade requires removal of certain i386 packages before update
Swapping to workstation sometimes may require you to use {{command|yum shell}} as it may require multiple packages to be swapped.
<pre>
yum remove perl.i386
TODO: Add list of bonobo i386 packages to remove here
</pre>
* Error: Missing Dependency: libpython2.3.so.1.0 is needed by package koffice
koffice was removed from Fedora Core and not moved to extras - so there's no way to complete an upgrade to FC4
without removing it. run:
<pre>
yum remove koffice
</pre>
then your update should complete.
 
* x86_64 systems seems to hang during "Running Transaction Test"
 
Seems related to bug [[rhbug:155730|155730]]  -- Maybe a update to the "rpm-4.3.3-3.0.fc3" (currently in updates-testing) might solve this. Ugly workaround (to be done as root):
<pre>
: > /var/log/lastlog
</pre>
 
* GPG check fails with this message :
<pre>
warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID db42a60e
public key not available for <some_package>
Retrieving GPG key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora
 
The GPG key at file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora (0x4F2A6FD2)
is already installed but is not the correct key for this package.
Check that this is the correct key for the "Fedora Core 4 - i386 - Base" repository.
</pre>
Edit /etc/yum.repos.d/fedora.repo and replace the line
<pre>
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora
</pre>
with:
<pre>
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY
</pre>
 
* SELinux gets corrupted. I had to re-download the selinux-policy-targeted RPM from my mirror, do a forced uninstall of the old package, clean out the .rpmnew and .rpmsave files then install the new policy. Then I had to run "/sbin/fixfiles relabel" and wait. If I didn't do that, I found I couldn't log in.
* If SELinux does give you problems, it can be disabled on bootup by pressing "a" on the grub bootup menu, then adding "enforcing=off" to the arguments list.
 
* RPM complains about missing diskspace, but there is a lot free. If you are really sure your diskspace is enough, set
<pre>
diskspacecheck=0
</code> in <code>/etc/yum.conf</code>.
The RPM transaction will need a lot of diskspace temporarily (much more than one might think), so be careful.
Don't forget to remove that later after the upgrade.
 
* Yum complains about files conflicting in the GCC package.  This system was upgraded from Fedora Core 1.  Remove the gcc32 package:
<pre>
sudo rpm -e gcc32
</pre>
 
* Some of your modules don't load after the upgrade.  When you investigate modprobe doesn't work as expected.  Run depmod:
<pre>
sudo depmod -ae -F /boot/System.map-[your <code>uname -a</code> kernel version here]
</pre>


* Yum has been reported to be hanging after upgrading. Updating the pysqlite package might fix it.
Many people report (e.g. bugs 1035326, 1044184, 1002331) that after upgrade some files have incorrect SELinux context. It is recommend to run:


=== Fedora Core 2 -> Fedora Core 3 ===
  # restorecon -R /


Go here for most of this info:

Revision as of 07:01, 30 June 2015


Warning.png
Upgrading using the yum method described here is not officially supported by FedoraQA. Please instead use the official upgrade tool, FedUp.

This page contains information explaining how to upgrade Fedora using yum.

Upgrading Fedora using yum directly

When upgrading with yum you don't get any help from FedUp, but with a typical system it might be able to upgrade systems remotely over ssh and with limited downtime. (You will still need to reboot to get the new kernel and system libraries/services running).

Although upgrades with yum do work, they are not explicitly tested as part of the release process by the Fedora QA and are not documented in the Fedora installation guide. If you are not prepared to resolve issues on your own if things break, you should probably use the recommended installation methods instead.}}

A live upgrade with yum usually works well with a typical installation and when following the advice below.

Participate

If you are upgrading using Yum and it shows any general dependency issues, please file them in http://bugzilla.redhat.com. But please read this page, all references pages and search the mailing list archives before filing bugs. And of course, please help keep this page updated.

If you want to help make live upgrades work smoothly, join the Live Upgrade Special Interest Group.

Instructions to upgrade using yum

1. Backup your system

Backup any personal data to an external hard drive or to another machine. If there is some unrecoverable error that requires a fresh install, you don't want to lose any data.

2. Read about common problems

Further down in this page there is a list of common problems specific to yum upgrades for specific versions. Some of them require attention before the upgrade.

General advice on upgrading Fedora can be found on the Upgrading page. You should also read the Installation Guide and Release Notes for the version you plan to upgrade to - they contain important information regarding upgrading issues. Finally, check the list of Common bugs.

3. Clean Stuff

Review and remove all .rpmsave and .rpmnew files before and after upgrading. (And if you have selinux enabled then remember to check security context if you move config files around.)

Idea.png
Find unused config files
Merge and resolve the changes found by the following script: yum install rpmconf; rpmconf -a Now find and remove old config which nobody owns: find /etc /var -name '*?.rpm?*'

Now is a good time to remove packages you don't use - especially non-standard packages.

Idea.png
Find and review "unused" packages
You can find packages not required by other packages with the tool package-cleanup from the yum-utils package: yum install yum-utils; package-cleanup --leaves. These packages could be candidates for removal, but check to see whether you use them directly or if they are used by applications not backed by rpm packages. Remove them with yum remove package-name-and-version.
Another useful tool for cleaning up unused packages is rpmreaper. It's an ncurses application that lets you view rpm dependency graph and mark packages for deletion. Marking one package can make other packages leaf, which you can see immediately, so you don't have to run the tool several times to get rid of whole sub-tree of unused packages. Install with: yum install rpmreaper.
Idea.png
Find and review "lost" packages
You can find orphaned packages (ie packages not in the repositories anymore) with: package-cleanup --orphans. This will also show packages which have been partially uninstalled but where the "%postun" script failed.

4. Do the upgrade

If you have 3rd party repositories configured, you may need to adjust them for the new Fedora version. If you switch from one Fedora release to another there is often nothing that needs to be done. If you switch to Rawhide from a standard Fedora release (or vice versa) then most of the time you will need to install the Rawhide release RPMs from the 3rd party repository as well (or the standard ones, if switching back).

Note that the upgrade is likely to fail if there are outdated dependencies from packages not backed by a yum repository or backed by a repository which isn't ready for the new version.

It is a good idea to do the upgrade outside the graphical environment. Log out of your graphical desktop and then

fedora-upgrade

A small script named fedora-upgrade is available which aims to automate the process outlined below. To run it, do the following

$ sudo yum install fedora-upgrade 
$ sudo fedora-upgrade


Alternatively, follow the manual steps:

Go to a text console

ctrl + alt + F2

(or)

log in as root, and go into multi-user.target

systemctl isolate multi-user.target

Update yum to latest version available in your Fedora version

# yum update yum

Install the new fedora gpg key for the version you are updating to

Keys you may find and verify at

https://fedoraproject.org/keys

or see a version specific update instructions at the bottom.

Clean the cache

Then remove all traces of the version you are leaving from the yum cache in /var/cache/yum.

# yum clean all

Upgrade all packages

Warning.png
Once a live upgrade is started, do not stop the upgrade by rebooting, killing the process, or by any other method until it is complete. Interrupting an upgrade will cause the affected system to be in a mixed state -- partially the old release and partially the new release. In this state, the system will not be reliable and will not operate as expected. You can try running yum distro-sync and package-cleanup --problems to try and fix the problems.
# yum --releasever=<release_number_you_want_to_sync_to> distro-sync
Warning.png
If you experience any dependency problems, you have to solve them manually. Most often it is enough to remove several problematic package(s). Be very careful when doing so however.

Note: While it is recommended to upgrade to intermediate releases if upgrading from an older release (for example upgrading from Fedora 19 to 20, then 20 to 21), depending on what version you are upgrading from, this step may fail with an error about GPG keys being in the wrong format. To overcome this, you can add the "--nogpgcheck" switch to the above yum distro-sync command.

5. Make sure Fedora is upgraded

Distro-sync will usually take care of upgrades for the third party repositories you have enabled as well. Confirm with

 yum repolist 

after the upgrade process is over. yum might complain about conflicts or requirements. That is probably because you have used non-standard repositories or installed non-standard packages manually. Try to guess which packages cause the problem (or at least is a part of the dependency chain) - uninstall them and try again. Remember to install the packages again if they are essential.

Ensure that all (new) essential packages from the new version are installed with

# yum groupupdate 'Minimal Install'

You might want to update other groups too, see

# yum grouplist

For example

# yum groupupdate "GNOME Desktop" \
    "Development Tools" "Sound and Video" \
    "Games and Entertainment" "Administration Tools" \
    "Office/Productivity" "System Tools"

6. Preparing for reboot

Before booting you should usually install the bootloader from your new grub by running

/usr/sbin/grub2-install BOOTDEVICE

- where BOOTDEVICE is usually /dev/sda (If you get an error '/dev/sda does not have any corresponding BIOS drive' from that, then try /usr/sbin/grub2-install --recheck /dev/sda).

It might also be necessary to update the grub config file:

cp --backup=numbered -a /boot/grub2/grub.cfg{,.bak} # create backup copy
/usr/sbin/grub2-mkconfig -o /boot/grub2/grub.cfg # update config file

Also, the order of init scripts could have changed from the previous version. A command to reset the order is:

cd /etc/rc.d/init.d; for f in *; do [ -x $f ] && /sbin/chkconfig $f resetpriorities; done

7. Cleanup your system

Again, cleanup your system as described in section 2. Also you might want to remove some cache files that are no longer used, for example files from older Fedora releases in the following directories:

  • /var/cache/yum
  • /var/cache/dnf
  • /var/cache/mock
  • /var/lib/mock

Version specific notes

From pre-release

If you are upgrading to a final release from an alpha, beta, preview, or other Rawhide release, please see Upgrading from pre-release to final.

To rawhide

Warning.png
Rawhide is the development branch of Fedora. It is meant to be used by developers and testers to provide feedback to the Fedora Project.

See the Rawhide release page for more information on Rawhide.

# dnf install dnf-plugins-core fedora-repos-rawhide
# dnf config-manager --set-disabled fedora updates updates-testing
# dnf config-manager --set-enabled rawhide
# dnf clean -q dbcache plugins metadata
# dnf --releasever=rawhide --setopt=deltarpm=false distro-sync --nogpgcheck

## Optional: it is generally advised to do a selinux autorelabel and reboot
# touch /.autorelabel


Fedora 21 -> Fedora 22

# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-22-$(uname -i)
# yum update yum
# yum clean all
# yum --releasever=22 distro-sync

Fedora 20 -> Fedora 21

# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-21-$(uname -i)
# yum update yum
# yum clean all
# yum --releasever=21 distro-sync

Fedora 21 split into different products. Execute one of those commands:

# yum install system-release-workstation
# yum install system-release-cloud
# yum install system-release-server

or this one if you want to have non-productized Fedora

# yum install system-release-nonproduct

If you change your mind, you can easily switch between products.

# yum swap system-release-cloud system-release-workstation

Swapping to workstation sometimes may require you to use yum shell as it may require multiple packages to be swapped.

Many people report (e.g. bugs 1035326, 1044184, 1002331) that after upgrade some files have incorrect SELinux context. It is recommend to run:

 # restorecon -R /

Appear to be enable to shutdown/reboot gracefully afterwards:

# shutdown -h now
Failed to start poweroff.target: Connection timed out
Failed to open /dev/initctl: No such device or address
Failed to talk to init daemon.
