Default Trouble with OP25...

I am trying to run scope.py on an Ubuntu machine (16.04.2 32-bit) and I keep receiving this traceback. Can anybody help me understand what it is not happy about? I know that the command instantiation is not perfect, but it doesn't matter what I type in the command line, it shows this error traceback. Thanks.

Casey

OP25 generally doesn't run on 16.04. One or two people have modded it to work, but it's non-trivial effort and requires installation of older wx libraries etc. By far the easiest thing to do is run ubuntu 14.04 and installation will be a snap.
