netinst will by default enable security updates and stable updates [1]
and has installed *during installation* packages from there (namely at least
libc6 (= 2.31-13+deb11u5).
Your "2." from above disabled those repositories, so apt can't use
those repositories anymore and will not able to resolve the dependencies.
This is the problem you are seeing.
