TP-Link AC600 not working on 20.04 [duplicate]

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.

You could install the latest drivers from this GitHub repo: https://github.com/aircrack-ng/rtl8812au.git

As per the repo, this is how you can install the drivers using DKMS method:

sudo apt update
sudo apt install dkms
git clone -b v5.6.4.2 https://github.com/aircrack-ng/rtl8812au.git
cd rtl8812au
sudo ./dkms-install.sh

Your USB WiFi adapter should be working now.
