When I try to run software-center from the terminal it gives me:
Traceback (most recent call last): File "/usr/bin/software-center", line 33, in <module> from gi.repository import Gtk File "/usr/lib/python2.7/dist-packages/gi/importer.py", line 76, in load_module dynamic_module._load() File "/usr/lib/python2.7/dist-packages/gi/module.py", line 224, in _load overrides_modules = __import__('gi.overrides', fromlist=[self._namespace]) File "/usr/lib/python2.7/dist-packages/gi/overrides/Gtk.py", line 523, in <module> class FontSelectionDialog(Gtk.FontSelectionDialog, Dialog): File "/usr/lib/python2.7/dist-packages/gi/module.py", line 105, in __getattr__ self.__name__, name)) AttributeError: 'gi.repository.Gtk' object has no attribute 'FontSelectionDialog'
A similar response is given when upgrade-manager or the advanced-settings (for Gnome Shell settings) is attempted. These are all the malfunctioning applications I know of right now, but there may be more. I'm running Ubuntu 11.10 and the Gnome-Shell environment. The error occurred after an automatic upgrade (I think). I have found people with the same or similar problem but none of the fixes has worked for me. I have tried reinstalling python2.7 and some of the other packages via Synaptic. I can still upgrade my distribution since I can run Ubuntu Tweak, but I'd like to sort this out. I have been using some of the experimental repositories for Gnome Shell development but since I figured this might be the reason for the error I purged (successfully I hope) and disabled them via Ubuntu Tweak.
Help on a basic knowledge level would be much appreciated.
