Ran into this after upgrading work computer from trusty to xenial. Tried all possible install alternatives for VirtualBox (official and repos), but module always refused to load.
In the end, as a hopefully temporary solution, disabled validation, booted, confirmed to disable secure boot and voila, everything loads. Not a very optimal solution, really the modules should just be signed for kernel 4.4.
This is what I did:
> sudo sudo mokutil --disable-validation
Curiously, after boot and confirming to disable secure boot, UEFI still shows it enabled and so does `sudo mokutil --sb-state`.. Some kind of "enabled but not validating modules" state?
