At some point the software updater vanished from the system. Now I reinstalled this package
sudo apt-get install update-manager
but when I try to call it with
I get an error
Traceback (most recent call last): File "/usr/bin/update-manager", line 28, in <module> from gi.repository import Gtk File "/usr/lib/python3/dist-packages/gi/__init__.py", line 42, in <module> from . import _gi ImportError: cannot import name '_gi'
Any idea how to fix this issue?
~$ python -V Python 3.6.8 ~$ python2 -V Python 2.7.12
The problem seems to be connected that I changed the default python to python3. But I want to keep python3 as the default python.
