This has happened to me a couple times, I dont have a clear answer how to fix it yet, but the dkms install hangs waiting for input at the secure-boot update screen, but it seems to open in different tty so I end up having to kill the process to regain control of the terminal. You can see virtualbox-dkms getting stuck easily if you look at the process tree. I'll try to attach more useful information after my next attempt.
