[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

[Mathew Hodson]

This was fixed in Xenial. The default is now to remove newly unused
dependencies after every unattended upgrade.

  [ Michael Vogt ]
  * Add `Unattended-Upgrade::Remove-New-Unused-Dependencies` that
    defaults to "yes". This ensures that older kernel
    get automatically cleaned up and /boot will not overflow.
    LP: #1267059
  * Remove downloaded deb packages after successful installs.
    This can be controlled via the option:
    `Unattended-Upgrade::Keep-Debs-After-Install`
    (Closes: #809428)
  * Only remove debs in the cache dir

  [ Steffen Köhler ]
  * Allow to configure sender email via `Unattended-Upgrade::Sender`

  [ Antti Riikonen ]
  * Minor typo fix in comment

  [ Cleto Martin ]
  * bugfix: non-ascii chars in dpkg log file crashes unattended upgrades
    Closes: #812857

  [ James Valleroy ]
  * Set debconf value for auto updates based on current configuration.

  [ Alexandre Detiste ]
  * update French transalation

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 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
