Desktop environment (KDE, LXQT…):
Command line (server) though there may be some X11 stuff
Description of the issue (screenshots if relevant):
Since a recent update, DNF doesn’t work anymore:
Traceback (most recent call last):

ImportError: /usr/lib64/libdnf.so.2: undefined symbol: modulemd_module_stream_v2_get_demodularized_rpms
Relevant informations (hardware involved, software version, logs or output…):
Hi @raphael. Just a guess. Perhaps download and install this with rpm?
Edit: But your omv-bug-report output shows lib64dnf2-0.69.0-1.x86_64 as installed. I’ll look some more but this may need a developer. But this looks like some package did not finish during the upgrade.
Hi @ben79 , I’ve already removed and reinstalled dnf and all dependencies (including this one) directly from mirror repos, using rpm command.
I still have the same message…
modulemd_module_stream_v2_get_demodularized_rpms is from /usr/lib64/libmodulemd.so.2 which is provided by lib64modulemd. So you may check if this library is effectively linked by libdnf.so:
ldd /usr/lib64/libdnf.so.2
or reinstall lib64modulemd from rpm.
Also there are some other errors make me as @ben79 there is something broken

Before I saw your repy, I tried to use zypper and it went well until went very bad: all was borked, all commands were failing (even simple like grep, rpm etc). At least I could revert to a backup I made just before.
I made the mistake not updating the server since January 2021 (the release was 4.2 at that time) because all was running smoothly. As it was a rolling, the update gap was certainly too big.
From the backup I made an upgrade to rock 4.3 and this time all has been working perfectly.
Thanks for this tip with ldd, I did not know, I’ll keep it.
