Title:
  apt autoremove is not removing unused kernels

Status in apt package in Ubuntu:
  New
Status in discover package in Ubuntu:
  New
Status in packagekit package in Ubuntu:
  New
Status in unattended-upgrades package in Ubuntu:
  Incomplete

Bug description:
  With the machines I help administer, we have been finding situations
  where the /boot directory is filling-up beyond 3 kernels on LUKS
  encrypted systems. apt autoremove is not removing old kernels as
  expected.

  This may also be an issue with unattended-upgrades since I found the
  following line commented-out by default:

  // Remove unused automatically installed kernel-related packages
  // (kernel images, kernel headers and kernel version locked tools).
  // Unattended-Upgrade::Remove-Unused-Kernel-Packages "true";

  We have had a system with as many as 15 kernel packages installed as a
  result of this not working as expected.

  The majority of these machines are using Discover to do their package
  upgrading, which uses PackageKit as its backend.
