Ubuntu Server 10.04 LTS to 12.04 Lots O Dragons

We ran into a TON of problems upgrading our ubuntu servers to the latest version of Ubuntu. We suffered everything from Kernel panics, to python issues, to broken upgrades mid-way through. It was a vastly different than the typical upgrade cycle we have been used to.

One perplexing issue was solved by the folks over at Operational Dynamics.


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

OD’s magical commands saved our bacon:


# apt-get install -o APT::Immediate-Configure=false -f apt python-minimal
# apt-get dist-upgrade


Thanks for the footwork and good luck to the rest of you upgrading your boxes (test, test, test, test).
