Recently I have been unable to install new versions of jAlbum (https://jalbum.net/en/software) with Ubuntu's Software installer, although installing with Terminal is possible using "sudo dpkg -i Downloads/jalbum_30.2-1_amd64.deb"
It seems that other jAlbum users also have the same problem https://jalbum.net/forum/thread.jspa?messageID=362852&tstart=0#362852
How to install it with the GUI software installer?
