Hi!
python-pip 25.3+dfsg-1 is causing other packages to FTBFS, if they
build-depends on python3-pip. 25.2+dfsg-1 was good.
It seems that pip keeps trying to connect to the internet even though sbuild
won't allow it. Then pip will just fail, throwing "could not find a version
that satisfies the requirement xxxxxxxx", even though the correct debian
packages were installed.
E.g., libselinux, FTBFS now as of 2025-11-21 with python-pip 25.3+dfsg-1 (but
was fine with 25.2+dfsg-1):
