Source: python2.7 Version: 2.7.18-1 Severity: serious Tags: patch Hi,
while analyzing piuparts buster->bullseye tests, I found some cases
where the Python 2 stack was not completely upgraded (some packages were
kept at the buster version even if a newer version was available in
bullseye). This happened because apt tried to keep some of the
unversioned python packages installed.
I've tried adding some Breaks and the attached patch fixed all of the
previously incomplete upgrades I tested.
I'm adding Breaks against python-minimal (<< 2.7.18) and
libpython-stdlib (<< 2.7.18), which are at the bottom of the unversioned
python stack. The version is chosen such that unversioned packages based
on the current version could still be built and installed locally ...
(Just after upgrading a clean buster system to bullseye the unversioned
python should be gone.)
I'm adding these Breaks to libpython2.7-minimal because it is the bottom
of the python2.7 stack still available in bullseye. (And I assume that
won't go away.)
I'm also adding these same Breaks to python2.7 which gets a higher score
by apt and therefore the removal of cruft packages more easily wins over
their preservation.
I'm attaching upgrade logs (with apt debug output if someone is
interested in scores and preoblem resolution) from ceph-common which is
one example affected by this. Here are some excepts:
Summary: apt tries to keep the cruft libpython-stdlib and python-minimal
packages installed and therefore cannot upgrade some python2 packages.
