(But there are still enough other packages that need to be fixed in some way, too.) After having looked into apt's scoring a bit, most of these paths are caused by #699759 apt: score computation may prefer obsolete installed packages over their successors and a small fix to the score computation solves this (by no longer doing something like score[pkg1] += abs(some_negative_score_from_pkg2) which makes packages with scores -1 and -2 more important than packages with score 0). But as upgrades need to work with squeeze's apt (and that cannot be changed), we need to work around this in wheezy, usually using high-score packages.

Bug#690172: gcc-4.7-base: adding Breaks: gcc-4.4-base ( 4.4.7) ?
Package: gcc-4.7-base Version: 4.7.2-4 Severity: whishlist Hi Matthias, breaking the old versions of gcj-4.4-base seems to work fine in sid (#677582). Thanks again for adding these. Now I have discovered some more upgrade issues involving some old libgnustep*, libobjc2 and gcc-4.4-base. apt chooses again to keep the old (squeeze) version of gcc-4.4-base instead of removing libobjc2. I think such incomplete upgrades of gcc-4.4-base could be fixed (better prevented) by adding another Breaks to gcc-4.7-base. But I'm not sure which versions to break: * gcc-4.4-base ( 4.4.7) # because 4.4.7 is in wheezy * gcc-4.4-base ( 4.4.6-9~) # because we break gcj-4.4-base ( 4.4.6-9~) * gcc-4.4-base ( 4.4.5-13~) # because libobjc2 was dropped in 4.4.5-13 and haven't made any tests with such a change so far. Adding such a Breaks would have solved #677582 as well. IMO distupgrades from squeeze should not involve keeping back upgradable packages. Packages that are no longer available are allowed to stay installed only if they don't block any other package from being upgraded. And unfortunately we can't fix squeeze's apt to make better choices. Andreas PS: I think my first approach of adding the Breaks: gcj-4.4-base ( something) in gcc-4.4-base stopped working at the time gcc-4.4-base got the Priority downgraded from required to optional, which shuffled the scores given by apt. And these score changes may be the reason for the new libgnustep* related problems, too. Andreas -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.
