Error during installation

[Bartosz2010]

Hello, For a long time this method works, although I had to repeat the installation of the drivers from time to time, the WiFi card stopped working.
But now, when I try to reinstall, an error pops up (I will only add that the WiFi card works under windows, so WiFi card is working)

Are you using the correct branch? It looks like you are on a 5.13 kernel, so you'll need the 5.8.7 branch

https://github.com/fastoe/RTL8812BU#for-kernel-511-or-later-please-clone-the-v587-branch

try that and see if it helps.
