[Bug 1183692] Re: Not enough disk space for kernel security update on /boot

[Franck]

This seems pretty bad, and mainly unmanageable by most average users.
A lot of question are generated, like these:
http://askubuntu.com/questions/342820/trying-to-update-but-not-enough-space-on-boot-answer-here
http://askubuntu.com/questions/298487/not-enough-free-disk-space-when-upgrading
http://askubuntu.com/questions/142926/cant-upgrade-due-to-low-disk-space-on-boot
http://ubuntuforums.org/showthread.php?t=2142894

and the most accepted answer is to blindly copy and paste this magic
incantation:

dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed
"s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^
]*\).*/\1/;/[0-9]/!d' | xargs sudo apt-get -y purge

A better solution has to be found, I can't explain to my Daddy why
"there is not enough disk space" :-)

Title:
  Not enough disk space for kernel security update on /boot

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

Bug description:
  Hi all

  I am using Ubuntu 12.10 and have just received the newest update
  notification from the update-manager marked as security updates. (This
  is NOT a release upgrade, but the regular security update)

  The update-manager tells me now that there is insufficient space on /boot to install these updates.
  The problem obviously is that too many kernels are installed: 3.5.0-17, 25, 26, 27, 28 and 30

  Which leaves 27MB space:
  Filesystem               Size  Used Avail Use% Mounted on
  /dev/sda1                228M  190M   27M  88% /boot

  Update Manager reports that it needs at least 33.2MB space for this
  update:

  "The upgrade needs a total of 33.2 M free space on disk '/boot'.
  Please free at least an additional 5,520 k of disk space on '/boot'.
  Empty your trash and remove temporary packages of former installations
  using 'sudo apt-get clean'."

  The hint in the message does not help for /boot.
  While I can fix this myself, I believe that this is not acceptable for an average end user to research and fix.
  Update-Manager should at least offer the option to remove old kernels (which it installed itself by security updates) in order for the security updates to proceed.

  
  I found an answer on AskUbuntu.com (http://askubuntu.com/questions/142926/cant-upgrade-due-to-low-disk-space-on-boot) which will help fix the issue. 

  TL;DR:

  -- 1 -- Release: 12.10
  -- 2 -- Installed Version of update-manager: 1:0.174.4
  -- 3 -- Expected:
  Security update should be installed. 
  -- 4 -- Happened:
  Failed because of insufficient disk space on /boot
  (Too many old kernels previously installed and not removed by update-manager)
