[Robert Euhus <1440608@xxxxxxxxxxxxxxxxxx>]

The problem is that on purge/removal the linux-image-extra package runs
all the kernel post-*install*-hooks in  /etc/kernel/postinst.d (as its
postrm hook), including the /etc/kernel/postinst.d/apt-auto-removal
hook. The 'to-be-removed'-version of the kernel is given as an argument
and thereby added to the list /etc/apt/apt.conf.d/01autoremove-kernels
of kernels which shall not be autoremoved. Which at this point is
clearly wrong, since we are probably just right now removing the
respective kernel (linux-image) version as well.

This bug was introduced as a fix to #1375310
(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1375310).

A fix is not so obvious for me, as running some  /etc/kernel/postinst.d/
hooks might be required upon removal of a specific version of the linux-
extra-image, if the corresponding linux-image package is not going to be
removed. But just running blindly all kernel-postinst hooks on removal
of a package does not really seem like a good idea to me.

Regards, Robert.

Title:
  /etc/kernel/postinst.d/apt-auto-removal wants to remove all kernels
  except the latest one

Bug description:
  After installing a 3rd kernel currently 3.19.0-12-generic, the
  /etc/apt/apt.conf.d/01autoremove-kernels file looks normal listing the
  3.19.0-11-generic and 3.19.0-12-generic with 3.19.0-10-generic listed
  to be autoremoved. But once autoremove is completed the machine
  requests to be rebooted and at that time the /etc/apt/apt.conf.d
  /01autoremove-kernels file lists the 3.19.0-12-generic and
  3.19.0-10-generic kernels. So upon rebooting the 3.19.0-11-generic is
  requested to be autoremoved leaving only one kernel the latest one
  3.19.0-12-generic.
