Pre-release version
Fedora 25 has not yet been released. During this pre-release period, this page will cover known issues in the Fedora 25 pre-releases. Issues that are fixed will be removed from the page once a fix is available (for instance, an issue that affects the Beta but is fixed in the final release will be removed at the time of that release).


Release Notes

Read the F25 general release announcement for specific information about changes in Fedora 25 and other general information.


My bug is not listed

Not every bug is listed in this page, but Bugzilla should be a comprehensive database of known bugs. This page is a sampling of the bugs most commonly discussed on our mailing lists and forums.

To see if your bug has already been reported, you can search Bugzilla. If it has not yet been reported, we encourage you to do so to help improve Fedora for yourself and others. A guide to Bugs and feature requests has been prepared to assist you.

If you believe an already-reported bug report should be added to this page because it is commonly encountered, you can:

  • Add it yourself, if you have wiki access. Common bugs instructions provides guidance on how to add an entry to the page correctly, but the most important thing is to make sure that the bug is listed - don't worry if you don't get the format quite right, we can clean it up later.
  • Or, add the CommonBugs keyword to the bug report. Someone from the QA team will then inspect the issue to determine whether the bug should be listed as a common bug. To expedite your request, please add a comment to the bug that includes
    1. a summary of the problem
    2. any known workarounds
    3. an assessment on the impact to Fedora users

For reference, you can query Bugzilla for bugs tagged CommonBugs:

  • CommonBugs? (bugs with CommonBugs keyword, but do not yet have a link to this page)

Installation issues

Dual booting Windows fails with 'relocation failed' error on some UEFI systems

link to this item - Bugzilla: #1347291

On some hardware, it's not possible to start Windows (possibly even some other OSes) from GRUB boot menu when booting over UEFI (it does not happen in BIOS mode). The message says error: relocation failed. The problem is still being investigated.

As a workaround, you can use your UEFI boot menu (the one-time boot menu is usually reachable via some hotkey like Esc, F8, F11, F12, etc) to boot Windows, which should work fine.

Advanced users can download and install grub2-2.02-0.25.fc23 (grub2 from Fedora 23), which should immediately fix the problem. However, when using this solution, the broken version of grub2 from Fedora 24 will be offered to you with every new system update, and you'll need to manually exclude it every time.

Windows entry is missing in grub when systems are installed on firmware RAID on UEFI system

link to this item - Bugzilla: #1347273

When Fedora is installed beside Windows on the firmware RAID and on UEFI it could happen that there will be Windows entry missing in grub menu.

This happens only with UEFI. User can use UEFI boot menu as a workaround (the one-time boot menu is usually reachable via some hotkey like Esc, F8, F11, F12, etc).

This bug appears just when UEFI and firmware RAID is used. So BIOS installations and normal disks (or with FW RAID turned off) shouldn't be affected.

Fedora fails to install on some RAID setups

link to this item - Bugzilla: #1333131 - Bugzilla: #1259953

On some setups, installing Fedora over existing firmware or software RAID can cause anaconda to crash. If you try to create a RAID array during setup on a system that has an existing RAID configuration using the drives from that previous RAID array, the newly-created one gets produced incorrectly and is unusable (and of course, the one you deleted is no longer there). User can restart and try again on the same selected drives (this time using free space) as workaround.

OS X volumes using Apple Core Storage are not recognized by the installer and shrinking them destroys all data

link to this item - Bugzilla: #1033778

The installer appears to support volume shrink for OS X volumes (Apple Core Storage) by offering a Shrink button and sizing slider in Automatic partitioning; and likewise allow numeric resizing in Manual partitioning. However, setting the installer to resize these volumes and proceeding with installation will result in complete data loss of the volume. Resize the volume in OS X's Disk Utility to create free space before proceeding with the installation of Fedora.

Software RAID (mdraid) from existing Fedora installations not recognized by Workstation/Live edition

link to this item - Bugzilla: #1225184

Installation from Workstation/Live image does not properly recognize existing Software RAID (mdraid) devices (e.g. from an existing Fedora installation). Those devices are listed as "Unknown" (0 bytes size) and cannot be used in the device selection dialogue which makes it effectively impossible to install Fedora 24 or keep existing data.

This bug exists since Fedora 22 (several Bugzilla reports have been filed for this issue but none has been processed yet).

The Server image does not have this problem and it can be used as a workaround to setup a minimal Server, and then install the "Workstation" package group from network remotely (using dnf). The result is not exactly the same and requires some minor additional manual work afterwards. (If anybody knows easier workarounds, please add to this section.)

Upgrade issues

DNF upgrade might remove essential system packages if you used PackageKit (GNOME Software, KDE Apper) in the past

link to this item - Bugzilla: #1259865

There was an unfortunate situation in the past few Fedora releases where PackageKit and DNF didn't work well together. If you installed something via PackageKit (used by GNOME Software or KDE Apper), it didn't mark such packages as "user installed" in the DNF database (which is used to differentiate user-requested packages from other packages installed purely as a dependency, but not explicitly requested by the user). Similarly, if you updated your system using PackageKit (GNOME offline updates, Apper), it erased such "user installed" flags from all updated packages. DNF then tries to remove any unnecessary packages during its next transaction (or when specifically asked using sudo dnf autoremove). This might lead to removing core system packages because DNF no longer sees them as "user installed" and considers them a no-longer-needed dependency. It is also possible that this might happen to you when performing a system upgrade to Fedora 25.

Fedora 25 hasn't been affected by this bug at all, and it was fixed in Fedora 23 and 24 since libhif-0.2.2-3. Current use of PackageKit (GNOME Software, Apper) should be safe. However, if you have ever used these tools in the past, you're strongly advised to fix your "user installed" database before you try to upgrade to Fedora 25:

  1. First, make sure your libhif package version is the same as described above or newer:
    rpm -q libhif

    If not, update it, and check again:

    sudo dnf --refresh update libhif
    Reboot after update.
  2. Then, mark all your current packages as "user installed" using this command:
    rpm -qa --qf '%{NAME}\n' | xargs sudo dnf mark install

Please note that this solution is slightly excessive, because you're going to end up with all your packages considered either system essential or user requested, and none of them is ever going to be removed as a no-longer-needed dependency. However, this is the only way how to be absolutely sure that you're not going to be affected by this issue, at a relatively small cost (some packages might stay on your disk unnecessarily). Power users can tweak this solution according to their needs.

Core system issues

GNOME issues

Offline updates in GNOME stop working after Google Chrome is installed

link to this item - Bugzilla: #1344643

If you install Google Chrome, it tries but fails to install a GPG key for its repository. This will break "offline update" functionality in GNOME Software (in this mode the updates are installed during a system reboot). Once a new google-chrome update is released, all future updates using GNOME Software will fail (including system updates unrelated to google-chrome, it's enough that the new google-chrome package is in the update set). This is not a problem for DNF, which will ask you to confirm the GPG key during the next google-chrome update.

In order to work around this, you need to confirm the GPG key for the google-chrome repo. You can do it using DNF, once a new google-chrome update is available. Simply update chrome using DNF and confirm the gpg key question:

$ sudo dnf update 'google-chrome*'

Alternatively, you can download the key and import it into RPM database (in this case you don't need to wait until new google-chrome update is available):

$ curl -O 'https://dl.google.com/linux/linux_signing_key.pub'
$ sudo rpmkeys --import ./linux_signing_key.pub

After this, offline updates using GNOME Software should start working again.

Plasma (KDE) issues

KDE Live image might not boot on some hardware when network is available

link to this item - Bugzilla: #1370222

We have identified a (possibly rare) race condition that make KDE Live image not boot into the graphics session on certain hardware, if network connection is available (only cable network tested). Since it is a race condition, just repeating the boots might get you into a functional KDE session (or might not). If you encounter this, please tell us in RHBZ #1370222. The simplest workaround is to unplug your network, boot KDE, and then plug your network back.

No installation icon on KDE desktop

link to this item - Bugzilla: #1350976

If you boot KDE Live image, you'll not see an icon for starting installation, that is usually placed on the desktop. Instead, you'll need to open the KDE menu in bottom left corner and you'll see the installation shortcut there (in Favorites section).

Other issues

Hibernation doesn't work from a standard install

link to this item - Bugzilla: #1206936

The systemd-hibernate generator used to handle resume from hibernate functionality expects a resume=/path/to/swap in the kernel args. Anaconda does not add this into /etc/default/grub and the dracut cmdline generator doesn't act in a way the systemd hibernate generator can locate the swap with the resume image.

To work around this, check the devmapper path to the swap via swapon -s command and add it to the GRUB_CMDLINE_LINUX entry in /etc/default/grub, then regenerate the grub.cfg file used:

  • Via grub2-mkconfig:
    • For BIOS systems:
      sudo grub2-mkconfig -o /boot/grub/grub.cfg
    • For EFI systems:
      sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
  • Via grubby:
    sudo grubby --args=resume=/path/to/swap --update-kernel=$(grubby --default-kernel)
