gui menu apps not launching

[noweare]

Hello,

Running LL 4.8 but in system is says Debian GNU/Linux buster/sid
which may raise a red flag to someone in the know.

I am finding that some of my gui menu apps are not launching
for example, firewall, gufw, printers.

Don't know what I did but I did upgrade from LL 4.4 to LL 4.8
a little while ago but I don't know if I have used these items after
the upgrade till i just found some are not launching.

But the common thread between the errors i am getting is that some of
the python modules that the intrepreter is looking for are missing like
gi and dbus

I am using Python3.6 is the python version being used for the python scripts.

If any of this sounds familiar I am all ears, otherwise I will spend a couple of days on it
and see if I can figure it out.

Thank in advance
Joe

I know this is not much info but if it sounds familiar I'd be all ears.

Thanks
