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.
- 1 Release Notes
- 2 My bug is not listed
- 3 Workstation (GNOME) issues
- 4 Upgrade issues
- 5 Other software issues
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
- a summary of the problem
- any known workarounds
- 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
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.instead of . 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.
Podman fails to run containers on upgraded systems (due to use of runc runtime with cgroups v2)
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 setting from to .
Other software issues
Dnfdragora shows spurious "DNF is locked by another process" error after successful update
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.
