This page documents common bugs in Fedora 23 and, if available, fixes or workarounds for these problems. If you find your problem in this page, do not file a bug for it, unless otherwise instructed. Where appropriate, a reference to the current bug(s) in Bugzilla is included.

Pre-release version
Fedora 23 has not yet been released. During this pre-release period, this page will cover known issues in the Fedora 23 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 F23_Alpha_release_announcement for specific information about changes in Fedora 23 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)
  • CommonBugs+(bugs with CommonBugs keyword and contain a link to this page)

Installation issues

Installer deletes EFI System Partition even in dual boot scenarios

link to this item - Bugzilla: #1183880

If you have several operating systems installed using UEFI boot (booting from EFI System Partition - ESP) and then go into the manual partitioning screen in the installer and select one of the operating systems to be deleted, the ESP will be deleted as well, even though it is required by the other operating systems.

If you need to perform such installation, don't delete the full partition tree under the to-be-deleted operating system, but delete all of its non-ESP partitions individually and leave ESP intact.

Installer does not always correctly compute the minimal required partition size

link to this item - Bugzilla: #1224048

The installer uses a set of heuristics to determine the minimal partition size to fit your installation in. Sometimes if you get very unlucky or you intentionally try to get the install partitions as small as possible, the installer might approve the partition size, but the installation fails at the beginning of the installation transaction (after your partitions have been created and formatted) due to insufficient disk size.

To be safe from this issue, please don't try to set an extremely small root partition (or any other system-critical partition, like /usr partition, if you decide to define one). Always plan for at least 500+MB of free disk space on such partitions (of course, in majority of cases you want much much more free space to have your system usable and useful).

Filesystems encrypted with passphrases using Cyrillic, Arabic or other switched keyboard layout characters cannot be decrypted at boot time

link to this item - Bugzilla: #681250

If the console keyboard layout for your language is 'switched' (you use a key combination to switch between typing Latin characters, and characters from your language), you will not be able to switch when entering encryption passphrases. Therefore, you will only be able to enter passphrases using whichever layout is the default. Usually, the Latin layout is the default. Therefore, if you are doing an encrypted installation using a language with a switched keyboard layout, we recommend you use only Latin characters in the passphrase.

Upgrade issues

FreeIPA fails to upgrade properly

link to this item - Bugzilla: #1274905

If you upgrade a system running FreeIPA to Fedora 23, FreeIPA will not start on the upgraded system. The logs will instruct you to run FreeIPA's upgrade process: Upgrade required: please run ipa-server-upgrade command. However, if you run the upgrade script, it will fail, and FreeIPA will still not work.

We strongly advise you do NOT upgrade FreeIPA servers to Fedora 23 until updates are available to fix several known issues in the upgrade process. If you have already updated the system but not yet run the ipa-server-upgrade script, we strongly recommend you do NOT run it yet: it is better to wait for the updates to be released first. If you have already run the upgrade script, you may be able to recover and get FreeIPA working by doing the following:

  • Edit /etc/dirsrv/slapd-(DOMAIN)/schema/99user.ldif
  • Find the entry (split across three lines) that starts attributeTypes: ( 2.16.840.1.113730.3.8.18.2.3 NAME 'ipaVaultPublicKey'
  • Replace it with:
attributeTypes: ( 2.16.840.1.113730.3.8.18.2.3 NAME 'ipaVaultPublicKey' DESC '
 IPA vault public key' EQUALITY octetStringMatch SYNTAX 1.3.6.1.4.1.1466.115.1
 21.1.40 X-ORIGIN ( 'IPA v4.2' 'user defined' ) )
  • Run pki-server migrate --tomcat 8
  • Run systemctl start pki-tomcatd@pki-tomcat.service
  • Re-run the upgrade script: ipa-server-upgrade

However, results may vary, and we strongly recommend waiting for the updated packages to be built, tested and made available.

Certain plymouth themes are problematic during system upgrade

link to this item - Bugzilla: #1267949

Certain plymouth (boot screen) themes are buggy when being inside the system upgrade environment. The known issues are with script and spinner themes - for the first one, the progress information scrolls off the screen soon, for the second one the screen stays black during the whole upgrade. The upgrade itself will execute just fine, but you won't see the progress properly (if this happened to you, do not force-reboot the computer in the middle of the operation, wait for it to finish, it will automatically reboot once the upgrade is done).

There is a fixed version of plymouth to resolve this issue. Even if you have it installed, you still need to execute sudo dracut -f manually to regenerate the ramdisk for your current kernel (or install a new kernel, which will do that automatically for you).

Alternatively, you can revert to the default theme before performing the upgrade:

sudo plymouth-set-default-theme charge
sudo dracut -f

Upgrade path for Vagrant broken (rubygem-celluloid retired)

link to this item - Bugzilla: #1275030

The package rubygem-celluloid was retired between Fedora 22 and Fedora 23, but no package was set to obsolete it. If you have the package installed when you try to upgrade to Fedora 23, and you do not use the --allowerasing option, the upgrade will fail to resolve dependencies. We recommend using --allowerasing to enable DNF to remove the rubygem-celluloid package and allow the upgrade to proceed, but please check the list of packages to be removed carefully and make sure the upgrade will not remove anything vital to you.

Core software issues

SELinux denial appears on application crash

link to this item - Bugzilla: #1276305

There is a known issue in Fedora 23's SELinux policy which causes a denial to occur often when an application crashes. It seems SELinux is forbidding the ABRT crash reporting tool from doing something it wants to do to analyze the crash. The denial will be SELinux is preventing abrt-hook-ccpp from using the 'sigchld' accesses on a process. The SELinux maintainers are working on a fix for this problem and it should be available soon.

GNOME issues

Logging out does not work when autologin enabled

link to this item - Bugzilla: #1245953

If you enable autologin in GNOME in Fedora 23, trying to log out will fail to work correctly; instead of returning to the login screen, you will get stuck at a black screen. We are working to fix this issue and an update should be available soon. Until then, we advise not using the autologin function of GNOME.

Initial user creation hands off to login screen (not desktop) and first attempt to log out fails

link to this item - Bugzilla: #1273112 - Bugzilla: #1272706

GNOME includes its own 'first boot' utility, gnome-initial-setup. If you install Workstation and do not create a user during the installation process, it will appear the first time you boot the installed system and require you to create a user account. When you complete the utility, it is intended to transfer you directly to the desktop logged in as the newly created user. However, sometimes, this does not work as intended and instead you see the GNOME login screen after creating the user account. When this happens, and you log in as the user you just created, your first attempt to log out will not work correctly, but instead will return you to a fresh logged in desktop session.

It appears that there is a timing problem, where gnome-initial-setup creates the logged in desktop session but does not successfully hand off to it, and when you then log in normally and log out, you are sent to the session created by gnome-initial-session.

This problem is a one-time issue and has no further effects. Once you log out a second time, everything will work normally from then on.

Plasma (KDE) issues

Initial setup sometimes starts in text mode instead of in graphics mode

link to this item - Bugzilla: #1185447

Sometimes happens that initial setup starts in text mode instead of graphical mode. Furthermode, it seems that text mode does not display properly. You can either reboot a few times, or log into a console and disable initial-setup-text.service by running command sudo systemctl disable initial-setup-text.service and restart. The graphical initial setup should be provided then.

Network issues

No network connection in VM when both host and guest installed from a live image

link to this item - Bugzilla: #1146232

If you install Fedora from a live image, and then create a virtual machine on it and install another Fedora from a live image as a guest, your networking in guest will probably not work. The reason is that libvirt virtual network address ranges are the same both in the host and the guest and clash. This does not happen if you install the libvirt packages in the guest manually at some point later (it is detected during package installation), only when you install from a live image.

If you don't need libvirt to work in the VM, you can remove libvirt networking there by running sudo virsh net-destroy default && sudo virsh net-undefine default, and then renewing the network connection in NetworkManager. If you need libvirt to work in VM, you need to edit its configuration files and assign a different IP range to it.

Hardware issues

The system reboots instead of shutting down

link to this item - Bugzilla: #1257131

On some specific Intel boards the system reboots after a few seconds instead of shutting down. This is related to the XHCI controller and will likely be fixed with newer kernel releases, but for now there is a workaround listed in the bug report to fix this issue.

Three monitors with an Intel GPU results in instability and display issues

link to this item - Bugzilla: #1275770

Since kernel 4.2, people with Intel graphics cards experience issues when they have 3 (or possibly more) monitors attached. The issues can range from desktop environment crashing, to monitor layout being reset from time to time, or certain monitors not waking up from sleep/locked desktop mode.

If you're affected, you can install and boot an older kernel 4.1 to work around this, or please wait until the issues are fixed in some future kernel update.

ARM issues

Fedora Server issues

Fedora Cloud issues

Atomic images have incorrect permissions on the /tmp directory

link to this item - Bugzilla: #1276775

The permissions of the /tmp dir on F23 atomic host RC10 are 755 when they should be 777. This breaks things that want to write to tmp but dont't have permissions to. To get around this: chmod 1777 /sysroot/tmp

docker 1.7.0 can't bind mount root dir into container

link to this item - Bugzilla: #1276776

Many super privileged containers need a bind mount of the root of the filesystem into the container. We can't do this with docker docker-1.7.0-22.gitdcff4e1.fc23.x86_64. Simply update docker to 1.8.0. You can wait until this hits the stable repos (it should be showing up soon) or build from source.
