Comment 1 for bug 1409877

Thanks for taking your time to report this issue and help making Ubuntu better.

I get the same error message when attempting to run mttroff 1.0+svn6432+dfsg-0ubuntu2 on 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 1409879 which seems to have the same underlying cause.)
