I am now trying to apply the steps to see if I can upgrade from any version of Ubuntu to the next release version. So far I have been able to successfully update from:

• v11.10
• v12.04

A couple of times I’ve had to run “dpkg –configure -a” (still trying to figure out what caused that need), but it has worked for the most part so far. My last test / trial is updating from v12.10 to v13.04.

Below is the process (list of steps) I am following (which is what I originally found when I needed to update from v12.04 to v12.10).

=====v12.04 to v12.10=====

Basically followed the post at Unixmen to upgrade my Lenovo ThinkPad to update / upgrade from v12.04 (Precise) to v12.10 (Quantal).

• sudo apt-get update && sudo apt-get upgrade
• sudo apt-get install update-manager-core
• sudo do-release-upgrade -d

I have read reviews that Quantal is “slower” than “Precise”, but I’m not really so much looking for performance issues as compatibility. My Production servers are still running v10.04 and I need to get them up graded to something more recent.

Am expecting to require a re-boot – we’ll see.

Time needed so far – about an hour.
