[Bug 1681566] Re: nvidia-375 DKMS module not recompiled on upgrade to 17.04

[Brian Murray]

I just did an upgrade from Y to Z with the virtualbox packages installed
and observed the same behavior as with the nvidia DKMS modules.

The modules were only built for the 4.8 kernel.

Title:
  nvidia-375 DKMS module not recompiled on upgrade to 17.04

Status in nvidia-graphics-drivers-375 package in Ubuntu:
  New
Status in ubuntu-release-upgrader package in Ubuntu:
  Confirmed
Status in virtualbox package in Ubuntu:
  Confirmed

Bug description:
  When upgrading from 16.10 to 17.04 using `update-manager -d`, the
  `nvidia-375` DKMS modules are not compiled for the new kernel.

  The result is that the user must run `apt install --reinstall
  nvidia-375` and reboot.

  To reproduce this:

  - Clean install of 16.10 on a system with NVIDIA graphics
  - Install `nvidia-375`
  - Run `update-manager -d`, complete all steps, then reboot
  - You will be unable to login until running `apt install --reinstall nvidia-375`
