Title:
  14.04 LTS Beta 2 Upgrade -> failed to update kernel, broke video
  drivers

Status in “ubuntu-release-upgrader” package in Ubuntu:
  Expired

Bug description:
  I was able to fix it by manually updating to kernel 3.13.0-20-generic.

  linux-headers-3.13.0-20  & linux-headers-3.13.0-20-generic was
  required to resolve the issue.

  What I expected to happen? Updating Ubuntu 14.04 LTS would not break
  my video drivers, preventing me from accessing my system without
  entering into recovery mode.

  What actually happened? Updated to Ubuntu 14.04 LTS, video drivers
  broke in an irrecoverable manner causing a black screen upon
  completion of booting, updated kernel and re-built the nvidia drivers.
