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.)

Found that gameapp was removed in this commit https://github.com/libavg/libavg/commit/7e1b4d89cdfe15d1ac37383375ce75adf7fdf04c

Looks like some demo program was ported to simply use app instead. Presumably something similar can be done for mttroff and sponc.

Since gameapp.py was intentionally removed from libavg upstream (see comment above), I reckon this issue won't be fixed in the libavg package. Instead the apps will need to be updated/ported.
