I know this is a really old bug but I just installed jfugue (on Ubuntu 18.04LTS) and I also ran into this problem. I was able to figure out what was wrong so I thought I'd post this in order to help someone else who may have googled and landed here:
The import line from the first couple of examples on the web site (http://www.jfugue.org/examples.html) is incorrect: import org.jfugue.player.Player; The correct line is: import org.jfugue.Player; I didn't try any of the other examples but they probably all have the same issue. p.s. I used the following command and the output gave me a hint of what the problem was: jar -tf /usr/share/java/jfugue.jar | grep -i player -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1026311 Title: package org.jfugue does not exist To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/jfugue/+bug/1026311/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
