What command did you use to upgrade the OS? You just showed the error message, but not what lead to the error.

The missing file should be at /usr/lib/x86_64-linux-gnu/perl5/5.40/AptPkg/Config.pm in Trixie.

I've the same error with the missing files /usr/lib/x86_64-linux-gnu/perl5/5.40/

I've the same error with the missing files /usr/lib/x86_64-linux-gnu/perl5/5.40/

as @LnxBil said - it would help a lot to know which commands you ran to get in that situation?
(and to provide /var/log/apt/term.log and history.log from that upgrade)

a very blind guess: did you maybe run `apt upgrade` instead of `apt dist-upgrade`?

Hello,
I have the same error while updating my Proxmox, the only thing that I could see is that the upgrade process is trying to search for the perl5/5.36 while I see when I restart after the update that I have perl5/5.40, and it seems that the problem could come from that. Do you have any information about that ?
In my case, I have used apt dist-upgrade.
If you need, I can provide the files term.log and history.log I just need to redo the update (it is in test so no problem with that).
Thank you
