I have a problem where I cannot use wifi or ethernet. I was going to try
this answer: https://unix.stackexchange.com/questions/416180/ubuntu-no-
wifi-adapter-found/423250#423250

But I can't get usb tethering to work, so I made a post here:

tethering-to-solve-problem

I recently installed Ubuntu 20.04 and this started happening.
Not exactly sure which package is responsible here.
I am making this bug report on the same pc except I am using an ubuntu installation thumbdrive. The live usb seems to recognize ethernet right away, but the one installed on my ssd doesn't.
