Hello. I had the same issue and I've found that one of the issues was that
the kernel headers were not correctly installed. I ran
apt install linux-headers-$(uname -r)
and after that finished the dkms driver was built.

I am not sure why this happens. Maybe some dependencies are missing?

I hope this helps you
