[Bug 2002865] Re: Othman does not run at all on Ubuntu 22.04

[Jeremy Bicha]

** Description changed:

+ Impact
+ ------
+ Othman won't run in Ubuntu 22.04 LTS because it tries to import Gtk with gobject-introspection without specifying a version. Ubuntu Desktop 22.04 LTS has both gir1.2-gtk-3.0 and gir1.2-gtk-4.0 installed by default. This causes Othman to try to load GTK4 but it is not compatible with GTK4.

+ Test Case
+ ---------
+ Install and run othman as demonstrated in the original bug report. The app should run normally.

+ What Could Go Wrong
+ -------------------
+ The app already does not work for most users. This is a trivial and correct fix.

  Hello.
  
  Othman, the open source Quran browser, does not run at all in Ubuntu
  22.04.
  
  After installing it with:
  $ sudo apt install othman
  
  If you try to run the program, you will get the following error:
  
- 
  mhsabbagh at ubuntu2204:~$ othman-browser

- However, this error seems to be in Ubuntu 22.04 only; I installed Debian 11 (which ships the exact same version of Othman, 0.6.0-2), and it runs without problems (image attached).

  I have found that if we just add these two lines to
  /usr/lib/python3/dist-packages/othman/gtkUi.py file (before the "from

  successfully:
  
  import gi
  gi.require_version('Gtk', '3.0')
  
  So it sounds like the issue is that since the Gtk version required isn't
  specified, it is trying to import Gtk 4.0 (which the program isn't
  designed to work with).
  
  Can anyone create a patch file with these two lines and update it in the
  Ubuntu package?
  
  Thanks.
