Broken Python install: "raise ValueError('Namespace %s not available' % namespace) ValueError: Namespace Gtk not available"

  • 772

I'm not sure exactly how I did it, but I think I broke my Python-GTK interface. I don't seem to be able to get applications written in Python using GTK libraries to run. Here is an example of three of them, gnome-tweaks, guake, and deluge-gtk: https://paste.ubuntu.com/p/HvpXYp2Xcf/

I'm sure more information is needed but I'm not entirely sure what to provide that isn't in the paste...

  1. removed the following files from /usr/local/lib/x86_64-linux-gnu

    -rw-r--r--  1 root root  480638 Apr 15 13:37 libgirepository-1.0.a
lrwxrwxrwx  1 root root      30 Apr 15 13:43 libgirepository-1.0.so -> ./libgirepository-1.0.so.1.0.0
lrwxrwxrwx  1 root root      30 Apr 15 13:43 libgirepository-1.0.so.1 -> ./libgirepository-1.0.so.1.0.0
-rw-r--r--  1 root root  212456 Apr 15 13:41 libgirepository-1.0.so.1.0.0

    and guake launched. Replaced them with the files from /usr/lib/local/x86_64-linux-gnu and set up symbolic links.

    Not sure how/why these were corrupted but it seems to have solved the problem.

    It seems that the point source of the problem is here:

    pwd: /usr/local/lib/x86_64-linux-gnu/x
root@computer# ./libgirepository-1.0.so.1.0.0 --version
