[Bug 1212716] [NEW] apt-get dselect-upgrade multi-arch bug while resolving dependencies

[James Troup]

Public bug reported:

dselect-upgrade in Ubuntu 12.04 LTS appears to have issues resolving
dependencies with multi-arch in play.  Starting from a clean state:

| root at lamassu:~# apt-get update > /dev/null; echo $?; apt-get dist-upgrade > /dev/null; echo $?; apt-get dselect-upgrade
| 0
| 0
| Reading package lists... Done
| Building dependency tree       
| Reading state information... Done
| 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
| root at lamassu:~# 

If I then ask for libvirt-bin to be installed and run dselect-upgrade,
it wanders off into the weeds of multiarch and by the time it wants to
come out, it's ready to toss ubuntu-minimal and ubuntu-standard
overboard to do so.

| root at lamassu:~# echo "libvirt-bin install" | dpkg --set-selections; apt-get dselect-upgrade
| Reading package lists... Done

| Reading state information... Done

(I know, dselect, haha.  We use it because it allows us to tell puppet
 to indicate which packages should be installed and then have a human
 interactively enact that by running 'apt-get dselect-upgrade'.  If
 there's an alternative way to do the same two stage process without
 using dselect-upgrade, I'd be happy to use that instead.)
