[volthor71]

Hi

I want to install the rtl8812au git to run a TP wifi key Link AC600 Archer T2U

I'm on LinuxMint 18.3 and i have error when i install rtl8812au with kernel 5.7.9

Here is the return of the code :

`~/rtl8812au $ sudo ./dkms-install.sh
About to run dkms install steps...

I have been using this driver with kernel 5.4 and have seen no issues, Distributions that use kernel 5.4 currently are Ubuntu 18.04 and 20.04 as well as Linux Mint 19.3 and 20.

I had the same problem with 5.6.4.2, if you try 5.7.0 it could work.
