Hello everybody, I'm using nvidia jetson nano and I want to install this driver, but I've encountered the following error: command: sudo ./dkms-install.sh

About to run dkms install steps...
Error! DKMS tree already contains: rtl8821CU-5.4.1

I've checked another issue, which another user encountered the problem while he forgotten to install bc. I'm using:

Nvidia's Ubuntu 18.04.4 LTS development kit
bc 1.07.1
linux kernel 4.9.140-tegra aarch64

How can I fix this?

Here https://www.armbian.com/jetson-nano/ it should just work out of the box. (kernel 5.10.y)
