Update from Fedora 42 → Fedora 43 leads to gdm core dumps

Hello everyone,

I have updated my FW13 AMD (7480U) via the Gnome App Center from Fedora 42 to Fedora 43. This initially failed because of some wine packages not being supported. This issue is also mentioned here and as suggested I uninstalled the offending packages and clicked again on the Update Fedora button in the App Center.

This time the update seemed to work as intended, but after restarting the laptop it never booted into a graphical user interface. Using Ctrl + fn + F3, I get access to a terminal and journalctl -b shows a core dump from gdm. The issue seemed identical to this one, posted on the Fedora forum, but none of the suggested solutions worked.

Surprising to me was also, that when I attempted to run sudo dnf distro-sync --refresh it was checking Fedora 42 repositories, not Fedora 43 repositories before then reporting multiple problems. I then followed suggestions from the Fedora forum and uninstalled packages with the .i686 architecture and a few other packages that caused conflicts and I considered not strictly necessary and then ran sudo dnf distro-sync --refresh --releasever=43. This time it was actually checking Fedora 43 repositories, but would have uninstalled several important programs (NetworkManager, sudo, systemd just to name a few), so I did not proceed.

The packages I manually uninstalled are the following, just in case I misjudged anything here:

  • wine-dxvk-dxgi
  • hyprland-qt-support
  • knighttime

The output from sudo dnf distro-sync --refresh --releasever=43is this
(adding --skip-broken returns the same output just without the suggestion)

Failed to resolve the transaction:
Problem: The operation would result in removing the following protected packages: NetworkManager, gnome-shell, grub2-tools-minimal, selinux-policy-targeted, setup, sudo, systemd, systemd-udev
You can try to add to command line: 
--skip-broken to skip uninstallable packages

I have already posted this in a response to the thread on the Fedora forum that I linked, but I hope that maybe someone here can help. I know I could just do a fresh install and I have a backup of everything that’s important, but it still would be a major inconvenience.

Bump because I’m desperate and nothing is still working

Backup your data and then install OS anew.
Its a quick fix.

This same thing happened to me on 2 machines - one I upgraded soon after 43 came available, and another today.

Both of these machines has had their share of upgrades – like since fedora 30

For me sudo authselect select local --force and then reboot helped.
