Problems updating rtl8821au - NEWBIE

[Rudizoon]

I update Linux Mint to 21 Vanessa, and my wifi stopped working. So I reverted back using TimeShift and found your github update page. Hopefully after updating the wifi driver, I can update the OS again, this time with wifi.

I followed your instructions, but now dkms status returns:
rtl8821au, 5.12.5.2, 5.4.0-144-generic, x86_64: installed (WARNING! Diff between built and installed module!)
rtl8821au, 5.8.2.3, 5.4.0-139-generic, x86_64: installed
rtl8821au, 5.8.2.3, 5.4.0-144-generic, x86_64: built

Not really what I expected.

What did I do wrong? And how do I fix this?

Many thanks in advance
Rudizoon

Hi!
Remove all rtl8821au WiFi drivers.

dkms remove -m rtl8821au -v 5.12.5.2 -k 5.4.0-144-generic
dkms remove -m rtl8821au -v 5.8.2.3 -k  5.4.0-139-generic
dkms remove -m rtl8821au -v 5.8.2.3 -k  5.4.0-144-generic

Update OS
Install WiFi rtl8821au again.
