I think the main error comes from /var/lib/dkms/sgx/1.36.2/source/dkms.conf does not exist. I have no idea why this error occurs. Do you have any solution for it?

Answer 1

I came across the same error a while ago. For me, removing dkms and reinstalling it worked.

Just execute:

sudo apt autoremove dkms
sudo apt install dkms

Hope this helps.
