Unable to launch Software Updater, Software & Updates, and Kazam in Ubuntu 18.04

I have a problem with some Ubuntu software. I cannot launch Software Updater, Software & Updates, and Kazam by clicking on the icons or right-clicking and then pressing New Window. In addition, I tried to launch the applications from the Ubuntu store. Unfortunately, the applications do not launch What should I do?

Personally, I do not want to reinstall Ubuntu 18.04. I will consider that solution as a last resort.

Potential Solutions

• Restarting it. I tried to restart my Ubuntu 18.04 browser and it does not fix the issue

• Reinstall Ubuntu

When I run /usr/bin/update-manager in terminal I get this output:

Traceback (most recent call last): File "/usr/bin/update-manager", line 38, in <module> from UpdateManager.UpdateManager import UpdateManager File "/usr/lib/python3/dist-packages/UpdateManager/UpdateManager.py", line 45, in <module> import dbus File "/usr/lib/python3/dist-packages/dbus/__init__.py", line 77, in <module> import dbus.types as types File "/usr/lib/python3/dist-packages/dbus/types.py", line 6, in <module> from _dbus_bindings import (
ModuleNotFoundError: No module named '_dbus_bindings'

Update:

I installed another application called package manager and that helps me update my packages. I realized that Livepatch does not launch.

Here's what I did:

1. I called sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 1

2. I called sudo update-alternatives --config python3

3. I select the alternative python path to be Python 3.6.
