Upgrade from Lucid to Precise fails

[Jan Ceulen]

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

SystemError: E:Sub-process /usr/bin/dpkg returned an error code (1)
Could not install upgrades
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...
