I am installing driver as title stated.
The issue is reported as unable to load kernel module.
I am assuming the kernel is installed already but not loaded.
mod probe cannot load module still.
Help me by giving a correct explanation of the issue or detailed instruction on how to fix it.
=== some info ===
Centos 7
Secure Kernel enabled
=== modprobe nvidia ===
modprobe: ERROR: could not insert ‘nvidia’: Required key not available
=== modinfo nvidia ===
