All you geeks out there, who have 3-4 boxes sitting around running different distros, here is an easy way to upgrade to Ubuntu Lucid Lynx 10.04 from Ubuntu Karmic Koala 9.10. Please note that Lucid Lynx is in alpha, so do it at your own risk.

Step 1: Open a terminal window on your Koala and type this:

   1: sudo sed -i 's/karmic/lucid/g' /etc/apt/sources.list && sudo aptitude update && sudo aptitude dist-upgrade

Step 2: Upgrade Karmic Koala to Lucid Lynx

   1: sudo aptitude install update-manager-core

   2: sudo do-release-upgrade -d

Since we already know that you are geek when you are reading this, all disclaimers are kept aside. Just kidding, upgrade on your own risk and don’t do production machines, since Lucid Lynx is still in alpha. Head over and download the Ubuntu 10.04 Lucid Lynx ISO, if you would prefer to do a fresh install.
