Description Ulrich Beckmann 2023-05-10 20:33:55 CEST
I have seen this confusing error message in the last line of the output of dnf in Cauldron quite a lot.

Complete!
Error: Missing /usr/lib64/gconv/gconv-modules.cache file.n[root@mga9-vm-alpha ~]#

The transaction itself was always complete, confirmed by dnf history and snapper. I did never spot any regression. 

Now the message occured again. My guess is that it occurs when there is an update of the package glibc. The file itself is not found. Previously it was there.

Thank you for the report.

Can you say how long you have noticed this? DNF was last updated in September 2022.

Your specific tests certainly point the finger of suspicion at glibc updates.

Assigning initially to tmb who updates glibc.
But if it is a DNF problem...

The message was well before Sept. 2022. Unfortunately this instance does not exist any longer.

Update to glibc-2.36-40.mga9.x86_64 on May 18 shows the issue again.

Our dnf is outdated https://github.com/rpm-software-management/dnf/releases/tag/4.17.0 but i not think that is the cause of the bug

Yeah I get segfaults on every new install now from DNF. Needs updating ASAP.

Please, open a new bug report.
I see nothing of the sort. I also use dnf for QA testing and 2 installations and 2 VMs.
