was heard to say:
I have also experienced this bug, with openoffice packages but also
other.
I have a feeling this is a separate problem from the original one,
since the submitter said the packages being removed weren't
garbage-collected. It looks like a legitimate bug, though.
I'm not quite sure about that. The symptoms are just the same, and the
submitters deleted packages are optional packages, too. Maybe it's
just a misunderstanding, or something.
I have debugged this and the problem seems to be in
aptitudeDepCache::apply_solution.
This function marks any package which is not kept or deleted as "auto",
which
means that, in my case, darcs will be marked as auto, and, not having
any
rdepends, immediately deselected. This also affects upgrades of non-auto
packages. This is, on my system a case of openoffice.org, because I have
openoffice.org-kde installed. This is an optional package, again no
rdepends.
So instead of upgrading as the resolver promissed, it will be deleted as
unused.
That sounds like a correct diagnosis.
When I commented out the line
MarkAuto(pkg, true);
it no longer deleted packages at will. However, I don't think this is
the
correct fix. It should mark new packages which were not selected by the
user only, but I don't know how to do it.
The attached patch should do the trick; it separates the case of
"install a new package" from the case of "install a different version of
an already-installed package". Does it work for you?
Well, yes and no. It does correctly the openoffice.org part, but the darcs
problem remains.
