Hey, just so you know ... this post is now about 12 years and 11 months old. Please keep that in mind as it very well may contain broken links and/or outdated information.

April is almost over, which means it’s time for another Ubuntu release! Today Canonical released Ubuntu 11.04 Natty Narwhal. As I am wont to do (with Maverick, Lucid, Karmic, Intrepid, etc.) I upgraded my server right away. The entire process took about 7 hours start to finish, but most of that was waiting for the 722mb to download (the download servers were understandably overloaded).

Like my previous server upgrades, the process itself was easy and straightforward. After the ‘do-release-upgrade‘ was complete, I re-applied my customizations to various configuration files, rebooted, and I was back in business on the new version. Also like my previous upgrades, I ran into a few snags:

• NUT 2.6.0 wouldn’t connect to my CyberPower UPS anymore: I found others reporting this issue and was able to compile 2.6.0 from source with a patch to get it working again.
• something “broke” in postfix with the upgrade from 2.7.1 to 2.8.2: the system couldn’t send e-mail until I added the port number (:25) to the end of the relayhost parameter. I couldn’t get it to work either running in the chroot jail or not, so it wouldn’t seem to be a permissions thing but I haven’t figured out the root cause yet.
• calibre wouldn’t run: python would throw a “magic number” error. I found a similar report in Launchpad but was able to fix this by simply removing calibre and then installing it again.
• I had to ‘apt-get install’ lsscsi to remove a minor error in phpSysInfo

So now I’m set until October, when Oneiric Ocelot will be released!
