Hey, just so you know ... this post is now about 11 years and 11 months old. Please keep that in mind as it very well may contain broken links and/or outdated information.

This week the latest LTS version of Ubuntu, 12.04 Precise Pangolin, was released. I waited a little bit for the initial download rush to die down (ok, only one day this time) and then took the plunge and upgraded.

As with my prior upgrades, the ‘do release-upgrade’ process itself was painless but I had a few post-installation issues:

• calibre wouldn’t start with a “ImportError: cannot import name detect_xml_encoding” error. Deleting /usr/lib/calibre/calibre/ebooks/chardet fixed this.
• zoneminder was completely messed up and wouldn’t run. After going down a seemingly unending (and increasingly frustrating) rabbit hole of package dependencies and missing libraries, I gave up trying to re-build it from source and just installed the package via ‘apt-get install zoneminder’. Even after that I had to clean up some of the mess left over by my previous from-source install, but I finally got it working again.

Coming this October: Quantal Quetzal!
