If you change your default keyboard layout in GNOME Settings, it will be changed immediately in your system, but it will not be changed immediately in the disk decryption dialog that is shown during boot (if you use disk encryption). The old keyboard layout will still be used for that disk decryption dialog until a new kernel is installed, only then it will be switched to the newly selected keyboard layout.

Revision as of 12:19, 27 April 2020

This page documents common bugs in Fedora 32 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.

Note.png
Pre-release version
Fedora 32 has not yet been released. During this pre-release period, this page will cover known issues in the Fedora 32 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 F32 Beta release announcement for specific information about changes in Fedora 32 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)

Core system issues

Colored output in DNF is hard to read

link to this item - Bugzilla: #1814563

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-2020-68aa5586ed

DNF terminal output is now colored in certain cases (e.g. colored search results, package names to be installed, package names to be removed, etc). Depending on your terminal color scheme, some output might be harder to read. There is an update available which should improve the readability considerably.

Installation issues

Memtest present on installation media often reboots/freezes

link to this item - Bugzilla: #1811353

Fedora installation media contain a "Run memory test" boot option that runs Memtest tool to check your memory for errors. Due to a bug, this tool often either freezes or reboots almost immediately. It might be particular to just certain hardware, but we have numerous reports of this happening. If you need to check your memory for errors, it's recommended to use a different source to create a Memtest bootable medium, and avoid using Fedora installation media for this.

Workstation (GNOME) issues

Changing default keyboard layout gets reflected during disk decryption only after next kernel update

link to this item - Bugzilla: #1405539

If you change your default keyboard layout in GNOME Settings, it will be changed immediately in your system, but it will not be changed immediately in the disk decryption dialog that is shown during boot (if you use disk encryption). The old keyboard layout will still be used for that disk decryption dialog until a new kernel is installed, only then it will be switched to the newly selected keyboard layout.

KDE issues

User switching/re-logging in KDE might often lead to a black/frozen screen

link to this item - Bugzilla: #1817708

We've identified several issues with user switching in KDE, which might lead to a black/frozen login screen:

  • Log out and immediately try to log back in using the same user.
  • Switch users (i.e. keep the current session running), and immediately try to log back in using the same user.
  • Switch users, log in as a second user, and then log out the second user.

The issue might occur just on certain systems and might depend on timing of your actions.

KDE login screen cannot handle expired passwords

link to this item - Bugzilla: #1819749

If your user password is configured to expire, you will not be able to log in using KDE login screen when it does. The login screen doesn't allow expired password to be changed (renewed). This is not a bug but a missing feature, it's not a regression from the past.

Upgrade issues

mDNS (multicast DNS) breaks on upgrade to Fedora 32

link to this item - Bugzilla: #1811935

The 'multicast DNS' feature enabled by default on Fedora, which allows you to reach another machine on the local network under the name <hostname>.local, breaks when upgrading to Fedora 32 beta. This happens because the /etc/nsswitch.conf file is modified incorrectly during the upgrade process. The problem can be resolved by editing the file manually and changing this line:

hosts:      files dns myhostname

back to this:

hosts:      files mdns4_minimal [NOTFOUND=return] dns myhostname

This is resolved in the Fedora 32 final release.

Other software issues

Trying to scroll with mouse wheel in inactive Firefox window results in back/forward instead

link to this item - Bugzilla: #1650051

When using the Wayland backend for Firefox, a known issue in GTK+ means that the Alt modifier key is still considered active in Firefox after you switch away from the window using the Alt+Tab shortcut. So if you then move the mouse over the inactive Firefox window (but do not click to activate it) and scroll the wheel, Firefox will treat this as holding down the Alt key and scrolling the wheel. By default, in Firefox, this is mapped to going 'back' and 'forward' in the page history, so instead of the page scrolling, you will rapidly move backwards or forwards through your page history.

If you find yourself frequently triggering this unwanted behaviour, you can work around it by navigating to about:config in Firefox and setting the value mousewheel.with_alt.action to 1 instead of 2. 1 sets the action when holding Alt and scrolling the wheel to be the same as when scrolling the wheel normally (it will scroll the page).
