=== Multiple issues with resizing existing volumes during installation ===
 
<small>[[Common F20 bugs#resize-bugs|link to this item]] - [[rhbug:1027714|Bugzilla: #1027714]] [[rhbug:1028110|Bugzilla: #1028110]] [[rhbug:1027682|Bugzilla: #1027682]] [[rhbug:1013586|Bugzilla: #1013586]] [[rhbug:1027947|Bugzilla: #1027947]] [[rhbug:1027965|Bugzilla: #1027965]]</small>
 
 
Multiple bugs have been reported in Fedora 20 Beta which are related to resizing existing storage volumes as a part of the installation process. Problematic scenarios include specifying a size for a partition which is larger than it could possibly be, attempting to resize partitions at the end of the disk that leave no padding space after the partition, choosing a new size for a volume and then changing your mind and returning it to the previous size, and others.
 
 
So far as we are aware, all the bugs manifest as crashes - either immediately on trying the problematic operation, or during the first stage of installation - and none of them result in a dangerous or incorrect resize operation actually being run, so there is no known risk of data loss. Nevertheless, we particularly stress the standard advice not to install Fedora 20 Beta to a system that contains existing data of value to you, and '''strongly''' advise you not to attempt to resize storage volumes that contain data of value to you using the Fedora 20 Beta installer.

<small>[[Common F20 bugs#grubby-update|link to this item]] - [[rhbug:864198|Bugzilla: #864198]]</small>
 
 
Placing /boot on a btrfs volume results in a kernel panic on reboot. Running either of the below commands (based on your setup) after a kernel update will fix this issue.
 
 
BIOS: {{command|grub2-mkconfig -o /boot/grub2/grub.cfg}}
 
 
UEFI: {{command|grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg}}
 
 
Then reboot your machine.

If you attempt to install Fedora 20 using a partially-complete kickstart - in particular, a kickstart which specifies a package set but no installation source or destination - you will find that the interactive process for setting those options behaves strangely. On the Installation Source spoke, you may not be able to use the default ''Closest mirror'' option. If you are affected by this problem, you can manually enter the URL of the Fedora 20 mirror list, and check the ''This URL refers to a mirror list.'' box. The URLs for the 64-bit and 32-bit mirror lists are <code>https://mirrors.fedoraproject.org/mirrorlist?repo=fedora-20&arch=x86_64</code> and <code>https://mirrors.fedoraproject.org/mirrorlist?repo=fedora-20&arch=i386</code> respectively.
 
  
The Installation Destination spoke appears to require you to complete it multiple times to complete configuration: each time it will set another element of the configuration. Even after doing this, you may find a bootloader target disk is not selected. To set one, first enter the ''Full disk summary and bootloader...'' screen and select not to install a bootloader, and complete the spoke once again. Then complete the spoke one more time, this time selecting the correct target disk for the bootloader, and the configuration should now be complete.

As these issues take some effort to work around, it may be a better idea simply to use a complete kickstart, or at least one which specifies an installation source and destination. The [[Anaconda/Kickstart]] page should help you with the required syntax.

Some testers have reported that attempting to run the Beagle Bone Black over HDMI doesn't currently work. At the moment to use the Beagle Bone Black you need a serial console. As on Fedora 20 Beta TC4 the Network/MMC/Serial console currently works and the BBone Black successfully boots. Further kernel updates to resolve the other outstanding issues will be forthcoming.

If you pick a non-US keyboard layout as the default or only layout during Fedora 20 Beta installation, that choice won't be honored after installation in virtual terminals or when decrypting filesystems during the boot process. Graphical sessions, however, will use the keyboard layout picked during installation.
 
 
Re-doing keyboard layout selection after installation may help to work around this issue, but we are still investigating the precise cause, workarounds, and solution.

This has been seen occasionally in testing on bare metal and more often in testing on virtual machines. It definitely affects GNOME and may affect other desktop environments.

When installing Fedora 20 Beta with the KDE desktop to a KVM-based virtual machine using the qxl virtual graphics adapter and driver, KDE will likely crash shortly after login.

If, during the 'initial setup' wizard that appears on first boot after a Fedora 20 Beta GNOME install, you enter the module for creating an 'online account' then change your mind and cancel the account creation, the tool may crash.

If this happens to you, you can safely delete one or other account once you have successfully completed the wizard, and it will not run again.
 
 
 
Other than this there should be no significant consequences of the bug: the crash occurs quite late in the process, and no actions from earlier in the process should be lost.

Installation issues

Problem with Installation Source spoke when installing from a partially complete kickstart

link to this item - Bugzilla: #972265

If you attempt to install Fedora 20 using a partially-complete kickstart - in particular, a kickstart which specifies a package set but no installation source - you will find that the interactive process for setting that option behaves strangely. On the Installation Source spoke, you may not be able to use the default Closest mirror option. If you are affected by this problem, you can manually enter the URL of the Fedora 20 mirror list, and check the This URL refers to a mirror list. box. The URLs for the 64-bit and 32-bit mirror lists are https://mirrors.fedoraproject.org/mirrorlist?repo=fedora-20&arch=x86_64 and https://mirrors.fedoraproject.org/mirrorlist?repo=fedora-20&arch=i386 respectively.

Hardware issues

ARM: HDMI output and USB peripherals not working on Beagle Bone Black

At the moment, to use the Beagle Bone Black, you will need a serial console. Post-release kernel updates are expected to resolve these and other outstanding issues; unofficial updated images may be made available by the Fedora ARM team for the convenience of Beagle Bone Black users.

Impatient and adventurous testers may wish to try installing a 3.12 kernel from the kernel-nodebug repository; it may resolve either or both of these issues, but there is a low expectation of support or testing of nodebug kernels.

Software issues

ZIP support in PHP

link to this item - Bugzilla: #999313

In Fedora 20, support from ZIP has been dropped from main php package and is now provided in a separate php-pecl-zip package.

If you need zip support, as for any other extension, run su -c 'yum install php-zip'.

GNOME Shell crashes after creating a keyring without a password

link to this item - Bugzilla: #1012844

In Fedora 20 with the GNOME desktop, if you attempt to create a new keyring without a password or change the password of your keyring to an empty string (you may do this from the "Passwords and Keys" application, or you may be prompted to create a keyring password the first time GNOME attempts to store some kind of key), the GNOME shell will crash. The workaround for this is to always use a password on your keyring.

An updated clutter package has been submitted to the updates-testing repository for testing. Users experiencing this problem are encouraged to test this update and report to Bodhi whether it solves the problem. However, note that one tester has reported that the update causes graphical corruption issues on an Intel video adapter. To test the update, run this command:
