Can you please clarify how exactly you run into this? I have just upgraded to this version, on a fully up to date sid system, and can't reproduce any of this. $ dpkg-query --show libpython3.9 libpython3.9:amd64 3.9.1-3 $ python3 -c 'import site' $ python3 -c 'import os' $ python3 -c 'from _collections_abc import _check_methods' $ I tried both on my main system, and on a clean sid container, and it just works.
