Title:
  Upgrade from Lucid to Precise fails

Status in “dpkg” package in Ubuntu:
  Confirmed

Bug description:
  After a long upgrade with no errors (guess 15 minutes) it stopped:

  Error...
  'E:Couldn't configure pre-depend multiarch-support for libapt-pkg4.12, probably a dependency cycle.'

  I was invited to report this as a bug.

  When (re)booting choosing Linux 3.2.0-30-generic fails (The CPU has been disabled by the guest...)
  Booting into Linux 2.6.32-42-server runs ok - system is 12.04.1 LTS.
  As far as I tested till now main functions do run (Apache 2.2.22, PHP 5.3.10  MySQL 5.5.24) and have been upgraded.

  I attach logs.tar (apt.log and mail.log from /var/log/dist-upgrade).

  What went wrong?
  I do have a backup of the machine before the upgrade.

  #edit
  apt-get -f install seems to solve the boot problem (works with 3.2.0-30 now).
  I'm still wondering if I am missing upgrades since the release-upgrade did not end succesfully...
