Common F28 bugs

In other languages: English (en) español (es) français (fr) [edit]

This page documents common bugs in Fedora 28 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 28 has not yet been released. During this pre-release period, this page will cover known issues in the Fedora 28 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 F28_Beta_release_announcement for specific information about changes in Fedora 28 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)

Installation issues

Switching keyboard layout with key combo does not work in Wayland

link to this item - Bugzilla: #1389959

If you're running Workstation Live install media and configure multiple languages in the installer, you won't be able to switch between them using the standard system shortcut (typically ⊞ Win+Space or Alt+⇧ Shift). However, you can still click on the language indicator in the installer with the mouse and that will switch the languages.

This does not affect other install media (KDE Live, DVD and netinst images).

Installer on several live images does not offer iSCSI support

link to this item - Bugzilla: #1395620 - Bugzilla: #1429132

On many or all Fedora Live images, the installer will not offer iSCSI functionality (the "Add iSCSI target" button will not appear in the 'Specialized & Network Disks' screen). You can avoid the problem by running sudo dnf install udisks2-iscsi from a console before starting the install process, or by installing from a dedicated installer image rather than a live image.

Upgrade issues

Upgrade from Fedora 26 might fail due to rich dependencies

link to this item - Bugzilla: #1552547

When you upgrade from Fedora 26 to Fedora 27 or 28, the transaction might get aborted immediately due to target packages having rich dependencies. The list of such packages as of Mar 2018 is available in bug 1552547. Eventually, the intended solution is to send updated dnf+rpm into Fedora 26 to handle this transaction properly. In the meantime, the easiest workaround is to remove affected packages before doing the upgrade, and install them back in the upgraded system.

GRUB update might fail if /boot is on XFS

link to this item - Bugzilla: #1227736

If you use XFS filesystem on /boot and upgrade your system, you might end up in a GRUB minimal prompt (just a command prompt, no kernel to choose from interactively) after the upgrade is complete. The problem is in the system rebooting while XFS is in dirty state and not all changes being saved to the filesystem yet.

In order to prevent this issue, you might try to disable plymouth (by removing rhgb kernel boot option) during the upgrade or uninstall it prior the upgrade (these workarounds were not tested).

If this already occurred to you, you should be able to fix the problem by booting a Live or rescue image, mounting the filesystem in question (which should replay the journal), perhaps running xfs_repair to make sure there are no more issues. In the worst case, you'll also need to fully re-install grub.

GNOME issues

Wayland issues

link to this item

Wayland is the replacement for the legacy X11 display stack. Although development has been rapid and Wayland is usable in most situations, some bugs remain. Please see the following link to learn the details:

• Wayland features status
• Known issues in Wayland
• Bug reports related to Wayland

Please check the list for your issue before you file a new bug, although if you're not sure, filing a new bug is the right thing to do.

Wayland is currently enabled by default only in GNOME. If you want to disable it, select GNOME on Xorg as session type when logging in (you only see this screen if your user has a password defined):

Autosuspend kicks in unexpectedly in GNOME

link to this item - Bugzilla: #1556790

GNOME 3.28 now automatically suspends the system after 20 minutes of user inactivity. However, this idleness timer is currently broken and if some application suppresses suspend and then releases it, the timer doesn't reset, and instead suspends your system immediately. This is most frequently visible when watching a movie in a movie player or a web browser - if you watch a video longer than the configured autosuspend timeout (20 minutes by default) and not perform any keyboard/mouse actions in the meantime, the system will autosuspend immediately after the movie ends, without giving you any option to prevent that.

The easiest workaround is to disable autosuspend in GNOME settings.

System automatically suspends after 20 minutes when in GDM, even when autosuspend is disabled

link to this item - Bugzilla: #1558485

GNOME 3.28 now automatically suspends the system after 20 minutes of user inactivity. Even if you disable/adjust this functionality in GNOME Settings, it only applies to your particular user session only, and does not affect the default system behavior, which is used when the local screen shows a GDM screen. This will affect you e.g. when you log out or switch between users, when you just start the machine without logging in and access it remotely (file sharing, ssh), etc. With some desktop environments, like Fluxbox, your system will also immediately suspend when you log out.

You can disable (or configure) auto-suspend system-wide by creating a file /etc/dconf/db/local.d/00-autosuspend with this or similar contents:

[org/gnome/settings-daemon/plugins/power]
# Do not autosuspend
sleep-inactive-ac-type='nothing'
sleep-inactive-battery-type='nothing'

and running:

sudo dconf update

Totem and Cheese fail on Wayland in virtual machines

link to this item - Bugzilla: #1467368

Totem (Videos) will fail to play media when using a Wayland session in virtual machines (applies to default libvirt VMs, but not VirtualBox). The audio will play, but neither video nor a totem window will appear. If you need to play media in this environment, please either use X11 session, or a different media player.

Cheese fails to start in a similar fashion. Because VMs usually don't have a webcam, this doesn't limit users in any way.

Scroll events are not sent into virtual machines from touchpad/trackpoint under Wayland

link to this item - Bugzilla: #1386602

Under Wayland, sending scroll events into a virtual machine works well when using the mouse, but doesn't work when using touchpad or trackpoint. As a workaround, switch to Xorg session on your host.

Content of VPN entry in GNOME status menu sometimes does not appear

link to this item - Bugzilla: #1497897

Some users have reported that, sometimes, the icon and text of the VPN entry in the GNOME status menu (the one that appears when you click the top-right of the screen) does not appear. Usually it will show a lock icon and the text 'VPN Off' (or information on any active VPN connection), but it appears that occasionally the icon and text do not appear; the menu just appears to contain an entirely empty row. The entry does function as intended.

No fix for this issue is yet known, but it has no functional impact - you can still use the 'empty' menu item.

Cinnamon in QEMU/KVM

Cinnamon Beta 1.3 live.iso only runs openbox

How to install:

1. liveuser login (no password)
2. openbox-terminal (right click on blank screen for menu)
3. su liveinst
4. after install reboot in terminal
5. login
6. openbox-terminal
7. su dnf update (349)
8. reboot to cinnamon (defaults to fallback mode cinnamon)

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)
