[Bug 1043026] [NEW] Failed upgrade from Lucid to Precise

[Launchpad Bug Tracker]

You have been subscribed to a public bug:


Attempting an upgrade from 10.04.4 LTS to 12.04 through the update manager results in a non-bootable system. The / partition is not found for some reason. Switching into the command line and performing an upgrade results in an error:

$ apt-get -f upgrade

E: Could not perform immediate configuration on 'python2.7-minimal'.
Please see man 5 apt.conf under APT::Immediate-Configure for details.
(2)

Attempting to reinstall python2.7-minimal (and python-minimal) didn't
work either:

$ apt-get install -o APT::Immediate-Configure=false -f --reinstall
python2.7-minimal

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or
specify a solution).

Attempting a do-release upgrade completes with errors, although the
system is now unbootable. I have attached the contents of /var/log/dist-
upgrade.
