[Bug 1054927] Re: Autoupdater fills /boot and crashes because old kernel images are never removed

[Hlini Melsteð Jóngeirsson]

This affects all my servers that I run and I regularly need to fix the
apt security updates because it fills the /boot folder. This affects a
lot of people and if you google "Ubuntu full /boot" you will see that
this affects a lot of people. If not all installations of Ubuntu servers
where automatic security updates are enabled.

Title:
  Autoupdater fills /boot and crashes because old kernel images are
  never removed

Status in “update-manager” package in Ubuntu:
  Confirmed

Bug description:
  Steps to reproduce:
  1) Install Ubuntu with the default LVM encryption recipe
  2) Set Ubuntu to automatically install security updates on the background
  3) Use ubuntu for 5 months

  Actual results:
  The system automatically installs security updates for the kernel under /boot. It's never removes previous kernel images. After about five months, the /boot partition created by the install recipe (i.e. sized according to the judgment of Ubuntu developers—not me) fills up and the unattended updater crashes during the next kernel update.

  Expected results:
  Expected the unattended updater to leave the nearest kernel and the previous one on /boot and to automatically remove older kernel images. Expected the system installer to set up /boot such that it never runs out of space when the system updater operates automatically.
