Wireless Dongle rtl8821AU

edit

Hello,

I cant get my wireless dongle to work.

I gets listed like that:

$ lsusb
Bus 001 Device 004: ID 0bda:a811 Realtek Semiconductor Corp.

$ dmesg
[  156.047670] usb 1-8: new high-speed USB device number 4 using xhci_hcd
[  156.245128] usb 1-8: New USB device found, idVendor=0bda, idProduct=a811
[  156.245131] usb 1-8: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[  156.245132] usb 1-8: Product: 802.11ac WLAN Adapter 
[  156.245134] usb 1-8: Manufacturer: Realtek 
[  156.245135] usb 1-8: SerialNumber: 00e04c000001

In the package there was a mini disc with driver. When I run install.sh, I get the following errors:
