Release Notes

Read the F24 general release announcement for specific information about changes in Fedora 24 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:

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 devices 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 devices (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.

LVM setup on encrypted PVs unrecognized after decryption

link to this item - Bugzilla: #1348688

Due to the issues with the new LVM DBus API, the installation fails to analyze an existing LVM setup on top of encrypted (LUKS) PVs after unlocking the LUKS device(s).

Updates image available
An installer update image has been made available which resolves this issue. To use it, hit e or Tab on the installer boot menu to edit the boot options, and add the following: inst.updates=http://vpodzime.fedorapeople.org/1348688_updates.img

This bug doesn't seem to occur with Live images (at least with Workstation Live), only netinst/Server images.

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

Rpmfusion packages block Fedora upgrade

link to this item

At the time of release, rpmfusion packages were blocking Fedora upgrades with a message similar to:

Error: Package a52dec-0.7.4-19.fc24.x86_64.rpm is not signed

This is a third-party repository issue outside of Fedora control. You can read more about possible solutions in this blog post. The repository maintainers are supposedly working on signing their repo, so that the issue disappears in the future. As of recently (mid-July) this has been fixed and RPMFusion packages are signed.

Upgrade from Fedora 24 fails if dnf-plugin-system-upgrade is not installed

link to this item - Bugzilla: #1395686

When upgrading from Fedora 24, it is possible to be in a situation where upgrade preparation - the dnf system-upgrade download step - works, but the actual upgrade - the dnf system-upgrade reboot step - does not. This occurs if you have the python3-dnf-plugin-system-upgrade package installed, but not the dnf-plugin-system-upgrade package.

If you encounter this issue, when you try the upgrade step, the system will start booting, but then appear to stall. If you hit Esc, you may see a message Reached target System Update. No progress information on the upgrade will appear.

To be absolutely sure this is the issue you are encountering, please leave the system for a long time - say, two or three hours - to ensure it is not just upgrading silently, as rebooting in the middle of an upgrade can cause the system to be entirely unusable.

But if there definitely appears to be no activity after several hours, shut the system down. Now either boot up and add rd.break to the boot parameters, boot the 'Rescue mode' from a Fedora install image, or boot from a live image. From the installed system root, remove the file /system-update. Now you should be able to boot the system normally again. Now install the package dnf-plugin-system-upgrade and retry the upgrade process.

Core system issues

DNF 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 24.

This is now fixed in Fedora 24 (since libhif-0.2.2-3.fc24) and Fedora 23 (since libhif-0.2.2-3.fc23). Future 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 start using DNF:

  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 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.

X crashes when systemd-udev package updated on systems with multiple graphics adapters (hybrid graphics)

link to this item - Bugzilla: #1341327 - Bugzilla: #1378974

Fix released
An update has been released to address this problem. However, as this issue manifests before the system can be updated, you may still have to work around it as described here.

If your system has multiple graphics adapters - the most common case being laptop 'hybrid graphics' (NVIDIA Optimus or AMD 'Dynamic Switchable Graphics') - and you update the systemd-udev package while X is running, it is highly likely that X will crash.

This may be a severe problem if you were running the update process inside of X (e.g. from a terminal app within your desktop). The X crash will kill the update process before the update has properly completed. This may leave you with inconsistencies in the package database, which can be difficult to recover from, and cause various other consequences (these will vary depending on which parts of the update process were not completed before the crash).

The crash is triggered when the systemd-udev-trigger.service service is restarted, so any other action which results in that happening may also cause X to crash on affected systems.

We strongly advise against running updates from a terminal window inside a graphical desktop. We advise against this in any case, but obviously there is a specific and severe reason to avoid it in this case. The safest way to apply updates on Fedora is using the 'offline updates' system, which applies updates by rebooting to a minimal environment, installing the updates, then rebooting to the usual environment.

If you update from the GNOME Software application on Fedora Workstation (GNOME), or by clicking on the 'reboot to install updates' notifications which are shown automatically from time to time on Workstation, you are using the 'offline updates' system and will not be affected by this bug.

On other desktops or non-graphical installs, you can use the offline updates system as follows:

sudo pkcon refresh force && \
sudo pkcon update --only-download && \
sudo pkcon offline-trigger && \
sudo systemctl reboot

If you do not want to use the offline update system, we strongly advise you at least update from a VT, instead of from a terminal app in a graphical desktop. That is, press ctrl-alt-f3 to get a console login prompt, log in, and run the update from the console. If you leave X running while the update runs on an affected system, it will still crash when the systemd-udev package is updated, but the update process will not crash (as it is not running in X) and will complete properly.

An update to resolve this particular issue was released, but due to the technical details of exactly how the bug is triggered, the update process that applies the fix will still be vulnerable to the bug. The fix can only prevent subsequent updates involving the systemd-udev package from triggering the bug. You must still take care when performing updates at least until after systemd-229-16.fc24 is installed, but it is really the best idea to always follow the guidelines explained here when updating the system.

RPM database errors after updating libdb

link to this item - Bugzilla: #1460303 - Bugzilla: #1394862

The changes made to libdb to address an issue with upgrading to Fedora 26+ have been reported to sometimes cause issues in the RPM database when updating libdb itself. When this happens, any subsequent package-related operation will likely fail, with some kind of message indicating that there are problems with the RPM database. This can potentially happen on update from any earlier libdb version to libdb-5.3.28-21 or libdb-5.3.28-23 or later, on update from libdb-5.3.28-21 to libdb-5.3.28-22, and on update from libdb-5.3.28-22 to libdb-5.3.28-23 or later.

Happily, the developers report that all such issues so far encountered should be easily, fully and safely recoverable. Usually simply running sudo rpm --rebuilddb should suffice; if not, try running sudo rm -rf /var/lib/rpm/__db* and then sudo rpm --rebuilddb again.

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.

Network configuration changes not always applies in GNOME control center

link to this item - Bugzilla: #1344788

In GNOME settings (control-center), network changes may not take effect for a connection using the Apply button - the configuration is not reloaded. Turn the connection off then back on again to reload the settings.

One of the affected options is "Use this connection only for resources on its network". This can be used for example when someone wants to make wireless connection default and still connect via wired connection for local resources.

Plasma (KDE) issues

Plasma crashes when switching users in VMs using QXL driver

link to this item - Bugzilla: #1293167

If you try to switch between different user accounts in Plasma while running in a virtual machine using the QXL driver, Plasma is likely to crash. This doesn't seem to happen when using a different video driver. It also doesn't affect bare metal machines (because those don't use QXL). The workaround is to use a different video driver in your VM.

Network issues

Hardware issues

Application issues

Firefox no longer plays H264 content using gstreamer, uses ffmpeg now

link to this item - Bugzilla: #1331496

Since Firefox 46, it no longer uses gstreamer to play non-free multimedia content (most often represented by H264 video codec), but uses ffmpeg instead. Instead of having gstreamer1-libav, now you need to have ffmpeg-libs installed if you want to be able to play such content in Firefox. Please note that ffmpeg is not distributed by Fedora and you need to obtain it yourself, if you wish to use it.

Docker fails to run anything if docker-1.10.3-3 was ever used

link to this item - Bugzilla: #1322909

There has been reported an issue with docker-1.10.3-3, which results in unusable docker. This issue persists even if docker is updated. Sufficient workaround should be to stop docker, remove directory /var/lib/docker and install newer docker. Users with lvm thin pool must recreate the pool since the removal of /var/lib/docker breaks it. For more, see RHBZ 1322909#c21.

ARM issues

bananapi: unable to pxe boot

link to this item - Bugzilla: #1329613

Some people are experiencing a problem with graphical PXE installation on Banana Pi. They are probably running into memory issues when 1G of RAM is not enough. The workaround is to append inst.text to kernel cmdline and proceed with text installation or install the system via VNC.

Fedora Server issues

FreeIPA fails to start after upgrade if initially installed with Fedora 21 or earlier

link to this item - Bugzilla: #1323400

Fix released
An update has been released to address this problem. After you update your system in your usual way, and possibly reboot, you should no longer be affected by it.

Between Fedora 21 and Fedora 22, FreeIPA was changed from using a file-based store for certificate profiles to a database store. Any FreeIPA server initially deployed under Fedora 21 or earlier would have had the file store, and would need to be migrated to the database store on upgrade to Fedora 22 or later.

Testing indicates that this migration was often not correctly performed on upgrade. With versions of pki-core after 10.2.6-12.fc22 (Fedora 22), 10.2.6-16.fc23 (Fedora 23), or 10.3.0.a1-2 (Fedora 24+), this prevents FreeIPA from starting successfully. With earlier versions, FreeIPA would start successfully, but some certificate operations would fail.

An update that fixes the upgrade migration process was released. If you have a server which was initially deployed with Fedora 21 or earlier and you waited until this update was released before upgrading, this bug should not affect you.

If you already hit this bug during upgrade, updating the package will not fix it. The symptom of this bug is that the pki-tomcatd@pki-tomcat.service service fails to start during FreeIPA initialization. If you run ipactl -d, you will see it repeatedly attempt to connection to https://(serverhostname):8443/ca/admin/ca/getStatus for some time, failing each time, then eventually time out.

If you are affected by the bug, first apply the update: run sudo dnf install yum, then sudo yum-deprecated --enablerepo=updates-testing update --advisory=FEDORA-2016-4d226a5f7e. Then, edit the file /etc/pki/pki-tomcat/ca/CS.cfg and replace the text subsystem.1.class=com.netscape.cmscore.profile.LDAPProfileSubsystem with subsystem.1.class=com.netscape.cmscore.profile.ProfileSubsystem. Finally, run sudo ipa-server-upgrade. This should correctly perform the migration, and FreeIPA should subsequently start correctly.

Fedora Cloud issues

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/grub2/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)

Resolved issues

Fedora Media Writer shows no writing progress on Fedora 22

If you used an older version of Fedora Media Writer (formerly liveusb-creator) on Fedora 22 to create a new bootable USB drive, no progress was displayed during the writing process. You had to wait until the dialog says "Finished". This issue was resolved in version 3.93.2; 3.93.3 was released for Fedora 22 on 2016-04-26, and 3.95.2 on 2016-06-23.

Non-live install with KDE, or installing KDE post-install, also installs Cinnamon

Due to some unfortunate interactions between the Fedora package group definitions and the libsolv dependency solver, if you installed the KDE package set from a traditional installer image (rather than the KDE live image), or tried to install KDE after initial system install by running sudo dnf groupinstall kde-desktop-environment or something similar, you got KDE...and also Cinnamon.

This should be resolved for new network installs of KDE, and kde-desktop-environment installs to already-deployed systems, since around 2016-09. If you were already affected by the issue, you will still have to remove the unwanted packages manually.
