[Bug 831768] Re: aptitude cannot handle conflicts with multiarch enabled

[Philip Muškovac]

While the situation has definitely improved as you can now install
multiarch packages from aptitude, the depenceny resolver is still a
mess. Attached is a log with a few packages having unresolved
dependencies because they're from a work-in-progress archive. The full
resolver gives many internal errors and ends with removing over 200
packages, aptitude safe-upgrade doesn't do anything but simply aborts as
it can't resolve the dependencies.

apt-get upgrade simply holds 8 packages back and upgrades the rest.
dist-upgrade holds 7 back and wants to remove a few which is still
reasonable.

  aptitude cannot handle conflicts with multiarch enabled

Bug description:
  TEST CASE:
  1. Enable multiarch (should be automatic on new oneiric systems)
  2. Install an i386 package on amd64 (like flashplugin-installer:i386)
  3. Mark something with a lot of dependencies for installation
  4. On the confirmation screen, try to remove on of the dependencies (aptitude will now fail to perform upgrades when there's a package conflict w/out removing the i386 libs)

  This renders aptitude painful on a multiarch enabled system (default
  in oneiric).
