How can I fix this problem?

Question

ubuntu

When I install programs through the terminal, I get this error:

При обработке следующих пакетов произошли ошибки:
 nvidia-dkms-390
 nvidia-driver-390
E: Sub-process /usr/bin/dpkg returned an error code (1)

And I also have such a problem, as if the driver was downloaded, but I decided to reinstall it, an error came out and the driver downloaded (I didn’t notice any significant problems after that), all these problems occurred after downloading the kernel : "xanmod" (It downloaded somehow not correctly , and I had to reinstall the drivers, and change the kernel manually to the standard one)

How can I fix this problem and continue to download programs calmly?

Answer 1

sudo apt install -f

Answer 2

Have you tried sudo apt-get upgrade? By the way, kernels from Ubuntu 20.04 work better with nvidia
