I tried to install the Linksys ac1200 on my ubuntu 21.10. I followed the procedure on this post on here by @David Foerster. I got error messages while running make:

Then while running sudo make install I got an another error:
install -p -m 644 rtl8812au.ko /lib/modules/5.13.0-21-generic/kernel/drivers/net/wireless/
install: cannot stat 'rtl8812au.ko': No such file or directory
make: *** [Makefile:1628: install] Error 1
Then I tried the procedure outlined in this post but without any success. This procedure went through without any errors, but the adapter still doesn't work. lsusb recognizes the device:
Bus 001 Device 008: ID 13b1:0045 Linksys WUSB6300 V2
If somebody could help me here, I'd appreciate that a lot. I would love to have it running. My best Rafa
