That is because secure boot is enabled. If you keep that "feature", you will NEVER be able to load any external module. There are two ways to disable secure boot: (1) change the BIOS setting, or (2) generate a kernel with that disabled.

@death2525 see Why do I get “Required key not available” when install 3rd party kernel modules or after a kernel upgrade?

I've disabled secure boot but I'm still getting this same error at this step. Other ideas?

Also thanks a ton for this, its worked for me for years on my lenovo yoga 11s with ubuntu but i updated something & now hitting this error.

Are you sure you disabled secure boot? That is the only thing that causes a required key not available message.

As far as I can tell:

The other possibility is that your distro is refusing to load modules that are not signed even though you have disabled secure boot. You would have to talk to them to determine if that is the case.
