I got this error during a release upgrade to 11.10 and I'm trying to
recover the upgrade process. I deleted a few old kernels to free up some
space on /boot and run "dpkg --configure -a".

Is this sufficient to end the upgrade process?

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.
