Thanks for taking your time to report this issue and help making Ubuntu better.
I get the same error message when attempting to run sponc 1.0+svn6822-0ubuntu2on Ubuntu Vivid. Looks like the underlying reason is that gameapp.py was removed from python-libavg as mentioned in the title. (Compare http://packages.ubuntu.com/precise/i386/python-libavg/filelist with http://packages.ubuntu.com/trusty/i386/python-libavg/filelist) I don't know whether it was removed completely or whether there is now a drop-in replacement which should be imported instead. (Also related to bug 1409877 which seems to have the same underlying cause.) ** Changed in: sponc (Ubuntu) Status: New => Confirmed ** Also affects: libavg (Ubuntu) Importance: Undecided Status: New ** Tags added: amd64 i386 trusty utopic vivid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1409879 Title: sponc can't be started: dependency libavg dropped gameapp To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libavg/+bug/1409879/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
