[Bug 1477455] Re: Incorrect instructions leave automatic updates blocked when /boot is full

[Jarno Suni]

Tyler Dinsmoor,
currently update-manager does not let you run update, if /boot is full, so I do not see where you patch is needed. It is just that update-manager can not recover from this issue or properly advice user to do something that helps.

Using synaptic or apt autoremove might not work in such a case
currently. linux-purge is designed to work better then.

Title:
  Incorrect instructions leave automatic updates blocked when /boot is
  full

Status in update-manager package in Ubuntu:

Status in update-manager source package in Artful:

Bug description:
  What happens:

  Default installations regularly fail package updates when /boot fills
  up. While the ultimate cause of this bug lies elsewhere, update-
  manager gives the user incorrect instructions when the failure occurs:

  "Not enough free disk space The upgrade needs a total of 104 M free
  space on disk '/boot'. Please free at least an additional 85.6 M of
  disk space on '/boot'. Empty your trash and remove temporary packages
  of former installations using 'sudo apt-get clean'."

  These instructions do not work, and software updates from this point
  on fail. The user is left vulnerable, unless they have knowledgeable
  assistance or are technically capable enough to research and fix the
  problem themselves.

  What should happen:

  update-manager should provide valid instructions for dealing with this
  well known problem, or better yet perform the operation itself. It is
  responsible for keeping  the users machine up to date, and needs to
  handle this and similar failures.
