I am guessing you are booting with Secure Boot enabled? If so, either
disable it or generate your own keys and add them to the firmware or
the MOK (Machine Owner Key) list. You can then sign the modules
yourself using that key.

You can find some information here:


"I'm ionized"
"Are you sure?"
"I'm positive."
