Installation Issues with AIR 1.5 on Linux?

We’ve been scouting blog posts, tweets and news articles and it seems that some users are facing problems trying to install AIR apps with the 1.5 Linux release.
If you had installed an AIR app with the Beta release of AIR, there’s some cleanup required before you can use the app with AIR 1.5.
We’ve put up a FAQ about installation issues on the AIR team blog – If you’re unable to use your favorite application with AIR 1.5, do have a look. After the requisite cleanup, TweetDeck 0.20, twhirl 0.8.7 etc. work great!
