I updated my home computer the other day, installing the latest 64-bit version of Linux Mint. This is my first foray into regularly using a 64-bit version of Linux, so I was not really prepared for some of the issues I experienced. Most of my issues (Amarok not working properly) were easily solved by simply adding some of the default Ubuntu repositories that are disabled by default in Mint.
However, I still had problems getting Adobe AIR and TweetDeck (or Seesmic Desktop, for that matter) to work correctly. After a bit of searching, I found that this is because Adobe hasn’t released a 64-bit version of Adobe AIR, and 64-bit Linux isn’t really prepared, out-of-the-box, to handle the 32-bit version.
I found an article in the Adobe knowledgebase explaining how to get Adobe AIR installed. Unfortunately, the link to the getlibs package in that article is outdated, and it was really difficult to find the real location of that file. I finally found it. This is, apparently, only a termporary location for the package, so I don’t know where it will end up afterwards. There is a topic in the Ubuntu forums where the location is discussed.
