Considering libpython-stdlib:amd64 11 as a solution to python2.7:amd64 23
Added libpython-stdlib:amd64 to the remove list

Fixing python2.7:amd64 via remove of libpython-stdlib:amd64
Fixing python2.7:amd64 via remove of python:amd64
Fixing python2.7:amd64 via remove of python-minimal:amd64
python2.7 in Bullseye explicitly Breaks: python (<< 2.7.18),
python-minimal (<< 2.7.18). This causes the removal of all packages that
Depend on python (including ganeti-2.16, python-simplejson etc).
Cheers,
