This should not happen with "recent" versions of aptitude, recent as in
the last 6 years at least, because solutions involving installations /
upgrades of non-default versions are kept in a different level and only
offered last, if at all, below upgrading to default versions, removing
it or keeping everything at the same version.

Have you experience this behaviour recently?


Cheers.
