This page documents common bugs in Fedora 24 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 24 has not yet been released. During this pre-release period, this page will cover known issues in the Fedora 24 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 F24_Alpha_release_announcement for specific information about changes in Fedora 24 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

32-bit Intel images do not boot

link to this item - Bugzilla: #1302071

For Fedora 24, the 32-bit Intel architecture (i686 / x86_32) is no longer considered 'release blocking'. As it happens, this is very visible with Fedora 24 Alpha, as it seems to be the case that all 32-bit Intel images are unusable. A kernel and/or kernel build environment issue seems to result in any attempt to boot a 32-bit Intel kernel failing with the error Failed to allocate space for phdrs.

There is no known workaround for this issue. Although support for 32-bit Intel is now no longer guaranteed, there are several people working to fix this issue, and we do hope to provide usable 32-bit Intel Fedora 24 images for Beta and Final. This issue will be updated as soon as usable images are available.

Installer crashes on wireless network discovery

link to this item - Bugzilla: #1262556

Several testers have reported that the Fedora 24 Alpha installer may crash on wireless network discovery. This crash may occur when entering the NETWORK & HOST NAME spoke on a system with a wifi adapter and no wired network connection, or may even occur as soon as you reach the hub screen.

If you are affected by this issue, the known workaround is to connect to a wired network during installation. Installing from a live image or the Server DVD image rather than a network install image may also help.

Installed system fails to boot on some hardware

link to this item - Bugzilla: #1318067

Pre-release Alpha testing has shown that on some hardware, a Fedora 24 Alpha installation will not boot successfully. The boot process hangs at a flashing cursor before the boot menu is displayed. So far, hardware reported to be affected includes Lenovo Thinkpad T450s, Lenovo Thinkpad T400, Lenovo Thinkpad X200, Dell T1500, and Dell T1600. We are still in the process of investigating this issue. So far the only known workaround is to replace the bootloader with an older version. One way to do this is to boot from a Fedora 23 rescue image, allow it to mount the Fedora 24 system (default is /mnt/sysimage) and run grub2-install --boot-directory=/mnt/sysimage/boot/ /dev/sda (if the system is installed to another disk, adjust the /dev/sda portion of the command).

Live images have no rescue kernel

link to this item - Bugzilla: #1317709

Due to a change in the image compose process, Fedora 24 Alpha live media contain no 'rescue' kernel. This means a system installed from a Fedora 24 Alpha live image will also have no 'rescue' kernel available for boot. The 'rescue' kernel's purpose is to provide a known-good fallback boot entry which also has a generic initramfs, rather than one tailored to the installed system's hardware (so if you change the system's hardware so much that the regular kernel no longer boots, the rescue kernel still should). If you would like to add a rescue kernel to a Fedora 24 Alpha system after installation from a live image, try this:

sudo dnf install dracut-config-rescue
sudo /etc/kernel/postinst.d/ $(uname -r) /boot/vmlinuz-$(uname -r)
sudo grub2-mkconfig -o /boot/grub2/grub.cfg

For UEFI, the final command should be sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg. Thanks to Andre Robatino for working out this procedure.

Initial setup utility displays in a small corner of the screen

link to this item - Bugzilla: #1160891

Fedora has a initial-setup tool which is run on first system boot in some cases. It does not run on minimal installations or GNOME (Workstation) installations (GNOME has its own separate tool called gnome-initial-setup), but does run on installs of most other desktops.

If you encounter this tool in graphical mode in Fedora 24 Alpha, you may notice it appears strangely - it initially appears very small and occupies only a corner of the screen, and the main interactions (setting a root password and creating a user account) are not immediately visible. You can find them by scrolling the window down. When you enter any spoke, the utility will become somewhat bigger, though still will not occupy the full screen.

This bug is purely cosmetic and the tool will work correctly as long as you manage to navigate it. We are working to resolve this issue for Fedora 24 Beta and Final.

Upgrade issues

GNOME issues

GNOME Settings Daemon crash on startup

link to this item - Bugzilla: #1288850

On some systems, the GNOME configuration manager, gnome-settings-daemon, crashes during system startup. This may prevent expected settings from being applied to the session (this can manifest in many ways, like fonts not appearing as expected). A crash notification will usually appear. If you are affected by this, you should be able to launch the daemon manually from a console with /usr/libexec/gnome-settings-daemon &. This issue is likely resolved in GNOME 3.20, which arrived too late for inclusion in Fedora 24 Alpha, and so should be addressed after install and update of the Alpha, and in the Beta release.

Crash on shutdown or restart

link to this item - Bugzilla: #1316311

Several Fedora 24 Alpha testers have reported a GNOME crash on session end (usually shutdown or restart). This crash may be somewhat hardware-specific. The issue is resolved in an upstream release that arrived too late for inclusion in Fedora 24 Alpha, so the crash should no longer occur on installed systems after an update. The crash does not have any known serious consequences and can be ignored.

Webkit crash when entering online account credentials or browsing GNOME Shell extensions

link to this item - Bugzilla: #1314658

Several Fedora 24 Alpha testers have reported crashes in the Webkit HTML rendering engine while using various GNOME desktop features that use it. Specific cases known to be affected include configuring online accounts (one reporter suggests a crash occurs when enabling caps lock while entering Facebook account credentials) and browsing GNOME Shell extensions.

At least some of the bugs have been resolved upstream, but the fixes have not yet worked their way downstream into Fedora yet.

Plasma (KDE) issues

Fedora 24 background not used in Plasma

link to this item - Bugzilla: #1320666

The intended Fedora 24 background is not used in the Fedora 24 Alpha Plasma spin. Instead an upstream default background is used. The Fedora KDE / Plasma team is aware of this issue and working to resolve it with an update and for Fedora 24 Beta.

Network issues

Hardware issues

ARM issues

Fedora Server issues

Fedora Cloud issues

LXDE issues

Default LXDE browser (Midori) is broken

link to this item - Bugzilla: #1319516 - Bugzilla: #1306144

The default browser on the Fedora 24 Alpha LXDE spin, Midori, does not launch (it will crash) when run normally. It can be launched from a console with midori --plain. You may also choose to install Firefox or another browser into the live environment, with sudo dnf install firefox; this will use some extra RAM.

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 in /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 and add this to the GRUB_CMDLINE_LINUX entry in /etc/default/grub then regenerate the grub.cfg file used:

Via grub2-mkconfig:
  For BIOS systems:
  grub2-mkconfig -o /boot/grub/grub.cfg

  For EFI systems:
  grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

Via grubby:
  grubby --args=resume=/path/to/swap --update-kernel=$(grubby --default-kernel)
