[Bug 798462] Re: update-manager's free space calculator for /boot seems insufficient

[Launchpad Bug Tracker]

This bug was fixed in the package update-manager - 1:0.151.8

---------------
update-manager (1:0.151.8) oneiric; urgency=low

  * DistUpgrade/DistUpgradeViewGtk.py:
    - set DPKG_UNTRANSLATED_MESSAGES to force untranslated dpkg
      terminal messages for easier package failure duplication
      detection
  * DistUpgrade/DistUpgradeCache.py:
    - when calculating the size of the space required in /boot use
      the size of the currently running kernel as the base and add
      a small safety margin (LP: #798462).
  * import new apt-btrfs-snapshot to fix crash for certain fstab
    entries (LP: #806065)

Title:
  update-manager's free space calculator for /boot seems insufficient

Status in “update-manager” package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: update-manager

  There are a number of initramfs-tools apport package bug reports from
  distribution upgrades regarding errors with a lack of free space on
  /boot.  Looking at DistUpgrade/DistUpgradeCache.py update-manager uses
  the following when calculating how much space the boot partition will
  need:

  KERNEL_INITRD_SIZE = 19 * 1024 * 1024

  The number 19 should probably be increased or as slangasek suggests "a
  much better predictor would be to check the size of the initrd for the
  current kernel".

  WORKAROUND:

  Remove unused kernels using computer janitor or manually free space on
  your partition containing the /boot file system.
