[Bug 1633903] Re: linux-image-4.8.0 not installed upon upgrade to yakkety if linux-generic not installed

[Brian Murray]

** Description changed:

- 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.
+ 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.
