It has been reported that in Fedora 31, if you run GNOME on X11 (not on Wayland) and configure a custom key combination for switching the keyboard layout via GNOME Tweak Tool or direct configuration editing, the custom combination will not work. Custom switcher combos do work in Wayland, and the several pre-defined combos available via the GNOME Control Center do work in both X11 and Wayland. Switching layout via the graphical menu in the top panel also works.

Revision as of 02:30, 17 September 2019

This page documents common bugs in Fedora 31 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 31 has not yet been released. During this pre-release period, this page will cover known issues in the Fedora 31 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 F31_Beta_release_announcement for specific information about changes in Fedora 31 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)

Workstation (GNOME) issues

GNOME Printers settings app can crash if you enter a typo when searching for a printer

link to this item - Bugzilla: #1750394

It has been reported that the GNOME Printers settings applet (accessible directly or via the Control Center) may crash if you enter a typo when searching for a printer, e.g. socket> instead of socket:. If you observe this applet crash unexpectedly, this may be the cause, so you may be able to avoid the problem by retrying and typing correctly.

Copy and paste and other agent features do not work with a SPICE-based virtual machine running Workstation

link to this item - Bugzilla: #1750120

Idea.png
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.

A tool called spice-vdagent is run automatically in SPICE-based virtual machines (e.g. those run by virt-manager or GNOME Boxes, usually) to enable features like copying and pasting from the host system into the virtual machine, and vice versa. In Fedora 31 Beta, this tool does not run correctly in GNOME, so all features enabled by the agent will not work. The update referenced above fixes this bug, but it was not included in the Beta release, so you will still encounter this bug when booting the Beta Workstation live image in a virtual machine. The bug will be resolved in future nightly live images, and in the Final live images.

Custom keyboard layout switch key combinations do not work in X11

link to this item - Bugzilla: #1743005

It has been reported that in Fedora 31, if you run GNOME on X11 (not on Wayland) and configure a custom key combination for switching the keyboard layout via GNOME Tweak Tool or direct configuration editing, the custom combination will not work. Custom switcher combos do work in Wayland, and the several pre-defined combos available via the GNOME Control Center do work in both X11 and Wayland. Switching layout via the graphical menu in the top panel also works.

KDE issues

Fedora 31 desktop background not used in KDE

link to this item - Bugzilla: #1749086

Idea.png
Update available for testing
A candidate fix for this issue 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. To test the update, run this command: sudo dnf --enablerepo=updates-testing update --advisory=FEDORA-2019-d7fbbec3ae

Fedora 31 Beta contains a bug which results in the wrong desktop background being used by default in KDE. It is not a Fedora background at all, in fact, but an upstream background called "Next". The update listed above will fix this bug, but only for users created after the update is installed. If you install using the Fedora 31 Beta KDE live image (or another KDE image from before the bug is resolved) and create a user before updating, the user's background will be set to the 'wrong' one and this will not be changed automatically when updating. You can easily switch to the correct background for affected user accounts in the KDE settings (or, of course, any other background you might prefer). This issue will be resolved for future nightly images and for the Final release.

Upgrade issues

Podman fails to run containers on upgraded systems (due to use of runc runtime with cgroups v2)

link to this item - Bugzilla: #1752040

If you upgrade a Fedora system where you have already installed and used podman to Fedora 31, after the upgrade it is likely podman will fail to launch containers any more. This is because on first use of podman in earlier Fedora releases a configuration file is written to the user's home directory which specifies that the runc runtime should be used to launch containers, but at present, runc does not work with version 2 of the kernel cgroups feature, as included in Fedora 31.

To resolve this issue, if you have not modified it in any other way, you can simply remove the affected file, with rm ~/.config/containers/libpod.conf. If you have modified the file in some other way, you can edit it and change the runtime setting from runc to crun.

Other software issues

Dnfdragora shows spurious "DNF is locked by another process" error after successful update

link to this item - Bugzilla: #1750575

It has been reported that the Dnfdragora package manager used on several desktops in Fedora 31 shows a spurious error message "DNF is locked by another process. dnfdragora will exit." after successfully updating the system. Please rest assured that there are no further consequences and this message can simply be safely ignored.
