Thanks for your debugging session.

I don't understand very well the relationship though -- in the
original message, when you paste the "versions", they are not marked
as auto-installed (you say "None of these three packages is marked as
manually installed:", but the information shows the contrary, so I
assume that you meant that).

Also, in the first "safe-upgrade", you don't mention if the packages
were marked as auto previously (either on purpose, or wrongly by
aptitude).

The commit above might be doing the wrong thing, but it doesn't have
much to do with holds but with marking the packages to "keep", for
example when one selects "Keep packages at current version" in the
interactive resolver.

It doesn't mark them unconditionally as automatic either, it tries to
force the Automatic parameter that was decided elsewhere (presumably,
determined to be the previous state before the current set of
decisions / pending actions was taken).


Cheers.
