OK, so:

Code:

EVDI kernel module built successfully

but:

Code:

Process: 5384 ExecStartPre=/sbin/modprobe evdi (code=exited, status=1/FAILURE)

because:

Code:

Aug 22 21:22:29 wx-ubuntu modprobe[5397]: modprobe: ERROR: could not insert 'evdi': Required key not

The evdi kernel module is not signed. Sign it yourself, or disable secure boot.

Cheers,
Michal

Hi Michal,

May I know how do I sign the evdi kernel module manually? I tried googling it but it did not really make much sense to me. Do appreciate your help on this

Since we're also using DKMS, the steps for signing evdi will be similar to VirtualBox modules:

Hope this helps.
