I don't know what broke it, but my python Gobject library is missing something ... When I try to run most tools like gnome-tweak-tool which require GTK, I get an error saying :
Traceback (most recent call last): File "/usr/bin/gnome-tweak-tool", line 24, in gi.require_version("Gtk", "3.0") AttributeError: 'module' object has no attribute 'require_version'
I tried to reinstall python-gobject, for python 2 and 3, install from the source the latest version etc etc. What am I missing !!! I feel like some library is missing which is optional and it causes this ?
