What was the issue with NetworkManager? Right now, everything is working fine on my machine.

Yeah. That case is amazing.

Firejail is great. I can recommend it.

I second this. XnView MP is one of the best free programs out there.

I am using Lutris for Windows games (sometimes Windows applications, too) almost exclusively on my rig. It works perfectly fine.

Yeah. Will do the update on my server playground today :)

The issue is resolved.

True :D but my link goes directly to the snapper section of the wiki^^.

SUSE & openSUSE also have a great documentation about the snapper snapshot tool which is also available in many distributions:

Arkenfox is not unmaintained but rolls a bit slower than Betterfox. But I will try Betterfox as well.
