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

[Darxus]

Workaround:

After trying the previously mentioned workaround, things were still
broken, complaining about qdbus.  So I did:

# If you have disabled multiarch by modifying /etc/dpkg/dpkg.cfg.d/multiarch, you must re-enable it temporarily.  The file should exist, and contain the line "foreign-architecture i386" (on my amd64 machine at least).
apt-get update
apt-get install qdbus # will remove qdbus:i386 and install qdbus
# Disable /etc/dpkg/dpkg.cfg.d/multiarch again - add a "#" at the beginning of the line it contains.
aptitude update
aptitude -f install # finally clean
aptitude dist-upgrade # also happy again

So this bug only affects people using 64 bit installs?

I'd still like a better understanding of what my options are if I need
to install 64 bit software.

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).
