Digitally sign drivers in Ubuntu 17

I came across the solution when installing Virtual box on Ubuntu but got the old

modprobe: ERROR: could not insert 'vboxdrv': Required key not available

I was having the same issue with my r8152 drivers for my Lenovo Thunderbolt 3 dock

This article got me 90% of the way to a solution but I wasn't able to load the driver.

The solution was fairly simple.

==Create a key, trust the key, use the key to sign the driver, reboot, Import the key during the MOK management boot screen, reboot, modprobe the driver, All good :)==
