Exception on Ubuntu 'module' has no attribute 'App'

[Will McGugan]

There seems to be an issue with the wx back end on Ubuntu. I get the following traceback:

$ python -m pyscreenshot.examples.showgrabfullscreen
Traceback (most recent call last):

I have no such problem on Ubuntu 15.10.

You can try these tests:

$ python -m pyscreenshot.check.versions
pyscreenshot         0.4
wx                   3.0.2.0
pygtk                2.28.6
pyqt                 not implemented
scrot                0.8
imagemagick          6.8.9
$ python -m pyscreenshot.check.showall

I think my installation of wx was broken. After uninstalling and re-installing wx, it worked.
