My OS: Ubuntu 20.04LTS
python --version: Command python not found
python3 --version: Python 3.8.2

Kazam was working well. I regularly upgrade packages using sudo apt-get update; sudo apt-get upgrade commands. I also update OS using update-manager -c command. So, one day kazam has stopped working. It gives the following error:

/usr/bin/kazam:32: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version('Gtk', '3.0') before import to ensure that the right version gets loaded.
  from gi.repository import Gtk
WARNING Kazam - Failed to correctly detect operating system.
Traceback (most recent call last):

    raise ImportError('cannot import name %s, '
ImportError: cannot import name GUdev, introspection typelib not found

I had run sudo ln -s /usr/bin/python3 /usr/bin/python for a different purpose. After some days the following happened: (Don't know how the system installed this python version)
python --version: Python 2.7.18rc1
Later I deleted the symbolic link too. So, now python command outputs Command not found.

  • I have the same problem. I followed possible solutions in https://askubuntu.com/questions/908620/kazam-main-window-not-showing and https://askubuntu.com/questions/982233/kazam-fails-with-pygiwarning-gtk-was-imported-without-specifying-a-version-fir but neither helped. – BubbleGuppies May 07 '20 at 08:49
  • I also tried. Didn't work for me too. – Utshaw May 07 '20 at 09:02

The errors aren't that serious but the fact that Kazam isn't working is. To start, first ignore the errors, then try this in a terminal:

sudo apt-get purge kazam

Then:

sudo apt-get install kazam

Then if sound isn't working follow this post:

Screen recording applications are not detecting audio in ubuntu 20.04

The problem with Kazam is it's open source software and the last time the source was updated is 2 years ago. So fiddling required.

I removed .confg for Kazam and it solved the problem.
