This week, in our Linux Page (in Spanish), we have written some easy instructions to repair the flash plugin on Ubuntu 9.04 Jaunty. In fact, after a brand new install on my Acer Aspire Athlon X2 I had big problems in visualizing Flash contents on Firefox 3. I tried to reinstall the plugin different times but the result did not change. Finally, reading a page in ubuntuforums.org I find the right solution for my problem. First of all you have to open Synaptic Package Manager (in System – Administration) and remove all the swfdec packages (in my case swfdec -mozilla and swfdec -gnome). Then, using the Terminal you have to type sudo apt-get install flashplugin-nonfree. Now you restart Firefox and Flash contents will be available again. We believe that this solution is really fast and practical but if you know a better one which could permit us not to install non free code please let us know.
