4.3.8.12175.20140902+dfsg-0ubuntu12 not working

[Pedro Palhares]

I upgraded to ubuntu 19.10 and rtl8812au is no longer working.
The driver builds with warnings, but when its loaded and the device is inserted,
it does not work and dmesg shows its broken.

It was working fine on 19.04.

Status changed to 'Confirmed' because the bug affects multiple users.
