[Bug 1357093] Re: Kernels not autoremoving, causing out of space error on LVM or Encrypted installation or on any installation, when /boot partition gets full

[Jackalux]

I don't have hardware that I imagine will run 16.xx so need this
addressed on older LTS versions.

My output for...
dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d'
 ... was 120 lines long!  I had to teach myself scripting to delete them all manually.  I only discovered the error after a different Linux machine I created (with a separate /boot) ran into the bug.

Deleting this junk freed 10GB of total disk space.

This is too much to ask of novice users and will stop Linux being more
widely adopted.  I'm not a complete Noob but this was annoying to deal
with... it will be impossible for others.

Title:
  Kernels not autoremoving, causing out of space error on LVM or
  Encrypted installation or on any installation, when /boot partition
  gets full

Status in unattended-upgrades:
  New
Status in unattended-upgrades package in Ubuntu:
  Fix Released

Bug description:
  Currently if one chooses to use LVM or encrypted install, a /boot
  partition is created of 236Mb

  Once kernel updates start being released this partition soon fills
  until people are left unable to upgrade.

  While you and I might know that we need to watch partition space, many
  of the people we have installing think that a windows disk is a disk
  and not a partition, education is probably the key - but in the
  meantime support venues keep needing to deal with the fact the
  partition is too small and/or old kernels are not purged as new ones
  install.

  For workaround and sytem repair, see
