Package: apt
Version: 0.9.7.7
Severity: important

Hi,

apt-get does not properly dist-upgrade a minimal squeeze system (with
recommends disabled) and db4.X-util installed to wheezy - apt prefers to
keep back db4.X-util and let libdb4.X installed, although there should
not be anything still depending on libdb4.X. The scores do not look
correct ...

Parts of the problemresolver debug output:

So far I failed to manually recompute the score "1" for libdb4.X.

Scoring was tuned in the meantime, I specifically remember:
* propagate a negative score point along breaks/conflicts

So, while this doesn't "solve" all instances of this problem, it should
at least help in this one and in the end it isn't really the fault of
apt as it is trying to protect users here by disliking removing packages
– package maintainers should just stop being on a cleanup frenzy for
nothing as it just trains users to ignore the REMOVE line in apt output
as most of them will be package renames anyway… expect in the cases
where real packages are removed and bad things happen.

Old versions/transitional packages should be kept around until a later
time in which the user decides to actively hunt for them instead of
trying to force apt to remove them in dist-upgrade already…


Best regards
