Title:
  linux-image-4.8.0 not installed upon upgrade to yakkety if linux-
  generic not installed

Status in ubuntu-release-upgrader package in Ubuntu:
  Fix Released
Status in ubuntu-release-upgrader source package in Yakkety:
  Fix Released

Bug description:
  Test Case
  ---------
  1) On an Ubuntu 16.04 system uninstall linux-generic
  2) Upgrade from 16.04 to 16.10
  3) Observe you are running a 4.4 kernel instead of a 4.8 one

  With the version of the ubuntu-release-upgrader from -proposed, run by
  executing do-release-upgrade -p, the linux-generic package will be
  installed before upgrade and you should then be running a 4.8 kernel
  after upgrade.

  Original Description
  --------------------
  Upon booting into the newly upgraded ubuntu yakkety system I noticed that the kernel option that grub listed was still linux-image-4.4.0-21-generic.  The system booted okay, but in aptitude  linux-image-4.4.0-21-generic was marked as obsolete (which lead to interesting problems later https://bugs.launchpad.net/ubuntu/+source/aptitude/+bug/1633897).  That is okay too, and while granted the linux-image-generic metapackage was not installed, linux-image-4.8.x was not installed by the update/upgrade process.  What the upgrade process should probably do is upgrade to the new kernel that comes with the particular flavour being upgraded to.
