You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 libpython3.11 : Depends: libpython3.11-stdlib (= 3.11.0~a7-1+focal1) but 3.11.0~a6-1+focal1 is installed
 libpython3.11-dev : Depends: libpython3.11-stdlib (= 3.11.0~a7-1+focal1) but 3.11.0~a6-1+focal1 is installed
 libpython3.11-stdlib : Depends: libpython3.11-minimal (= 3.11.0~a6-1+focal1) but 3.11.0~a7-1+focal1 is installed
 python3.11 : Depends: libpython3.11-stdlib (= 3.11.0~a7-1+focal1) but 3.11.0~a6-1+focal1 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

I have not yet ran the suggested command as I do not know whether this is a glitch on my system or there is an actual missing dependency.

When I do an apt-cache search --full I get this..

So indeed the issue is that libpython3.11-stdlib was not updated - for reasons. The other errors were consequential errors.

Running sudo apt --fix-broken install indeed fixed the issue.

Closing as this has been resolved.

P.S.: Do you have an idea why this error happened?

no idea, usually when I get that error I try each individual "won't be installed" package until it shows me the actual error -- unfortunately that'll all be lost with the "--fix-broken"
