Still no luck to install the driver for TP-LINK Archer T2U on fresh installed Ubuntu 18.10. I checked and tried all other posts in here, but I had no luck.
The installation process was like this:
# sudo cp -R . /usr/src/rtl8812AU_8821AU_linux-1.0
# sudo dkms add -m rtl8812AU_8821AU_linux -v 1.0
# sudo dkms build -m rtl8812AU_8821AU_linux -v 1.0
# sudo dkms install -m rtl8812AU_8821AU_linux -v 1.0
After rebooting there was still no Wi-Fi:
