There exists no official flash package available for the 64bit architecture with Ubuntu and Kubuntu. If you click the add plugin button when visiting a page with flash, you are taken to the official Flash site and will soon notice that there are no available 64bit downloads here either. There are some workarounds on ubuntu forums, however, they don't always seem to work and get complicated if you have compiled your own 32bit Firefox. We have been using both the official 64bit Firefox package from the Kubuntu repositories as well as a modified 32bit version I built quite a while ago to get around some stability issues with the 64bit version. So after about a year without flash support, we finally took the plunge and have built a quick and easy solution. Read on to see how you can add Flash and Java support to your 64bit system in under 1 minute. [Update] At the end of the article, you will see how we can install a 32bit version of Firefox.
