I recently discovered that on UBUNTU I could no longer install new versions of jAlbum via the old Software Updater.
If any other Ubuntu users are having the same problem, it is easy enough to install jAlbum from the Terminal with the following command
sudo dpkg -i Downloads/jalbum_30.2-1_amd64.deb
Replace "Downloads/jalbum_30.2-1_amd64.deb" with the path to the deb file that you have downloaded, of course
