Ubuntu – Driver for the TP-Link AC600 Archer T2U Nano, on Kubuntu 18.04 Previous fix from June 6 didn’t work for me

TP-Link AC600 Archer T2U Nano driver for Ubuntu 18.04
I could not get this fix to work for me. I am in and out of Ubuntu; it's been at least 5 years since I have worked in Ubuntu and I swear it used to be easier to find drivers and almost anything I needed back then.
Here's the locations of my t2u:

     Bus 002 Device 007: ID 2357:0120

When I tried fixes from above I get:

Any help would be amazing.
I tried using drivers from cd, tp link website, and the fix above.
Thank you.
