I did a fresh install of Ubuntu 9.10 Karmic Koala a few days ago. I know its a bit late, but the reason why I didn’t do it earlier was because I didn’t want to mess up my customized Ubuntu “Mac” desktop. What made me decide to do a fresh install was because my old Ubuntu partition was only 5 GB and I was already running out of space. This time, I created a bigger partition – 40 GB. Anyways, the upgrade was quick and it went smoothly. Since it was a fresh install, I had to reconfigure everything and reinstall all the programs and applications that I need. One of it was Adobe AIR which I need to run my Twitter client of choice – TweetDeck.

Installing Adobe AIR on Ubuntu can be quite tricky if you’re not quite familiar with the commands and if you’re new to Linux/Ubuntu. So for the sake of those users, I’m sharing this short step-by-step tutorial on how to install Adobe AIR on Ubuntu.
