I had the same issue, but I think once you disable security boot in BIOS, the error goes away.

I figured it out. The problem has you mentioned is that with secure boot enabled you can't install the EVDI kernel because it is not signed. So you have two options one as already been mentioned is deactivate secure boot.

The other alternative and in my opinion better alternative is to sign the kernel yourself

Hi all,

I have the same issue. I managed to have it working by disabling the bios security. However, I would like to self sign the module to have the secure version of the boot.

Is there someone with the instructions/ steps to follow to sign the module that is causing the problem? Any reply is much appreciated.

Thanks in advance.

Andrea

Hi,

Some hints for secure boot are given in the "important note" in the sticky post with release announcements.

Cheers,
Michal

Hi Michal,

thanks for your post. Actually I read it and I performed the steps in the ubuntu guide/example related to virtual box.
But I am kind of stuck when I have to provide the path and name of the module to sign. Can you shed some light on it?

Thanks in advance

Andrea
