SDDM/GDM Fail after upgrading via DNF5 from F39 to F40

Project Discussion
1

I just upgraded on my Laptop and am getting the black screen. It’s failing on both GDM and SDDM. I’ve included info from coredumpinfo. Has anyone else had this issue, I haven’t opened a bugzilla yet, but can. System works fine on F39.

Well, that was weird. I fixed the issue. Apparently, the package bismuth didn’t upgrade which caused kdecoration not to upgrade, which then caused many other packages not to upgrade. To fix, I deleted bismuth, then ran dnf upgrade again and that resolved the issue. I would have thought the upgrade should have failed to catch that, but it didn’t. I was experimenting with using dnf5 for the upgrade, maybe that had something to do with it. Anyway, all fixed now.

Edit: I’ve opened up a bug:
https://bugzilla.redhat.com/show_bug.cgi?id=2273749

I started to think hey, this passed the transaction check and then went on to install a half upgraded system - should not have done that. Should have been caught by transaction check.

I was able to recreate on a virtual machine and also determined this is an issue with DNF5. Until this is resolved, I would not use DNF5 for system-upgrades. DNF5 has a serious issue with the transaction check process. See the bug report for more information.

Greatly appreciate that info !

It seems that this particular issue is caused by problem when versions of kde libraries are mixed. The issue is caused by the packages not declaring the required dependencies, so this could be considered a bug in the package. In practice, it is often hard to catch, because people tend to upgrade all related packages together, so realistically such issues will happen occasionally when some other package prevents part of the upgrade from happening.

It has nothing to do with dnf5.

no, it really does have a lot to do with dnf5. There is indeed a dependency issue in the packages, but dnf5 did not behave at all correctly in dealing with it. dnf devs are treating this as a high priority issue.

The patched version is now available in copr, if you don’t want to wait for it to appear in updates-testing:

dnf copr enable rpmsoftwaremanagement/dnf5-unstable

Tested in a VM and looks good:

Thanks everyone for the quick response. Much appreciated!
