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

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)

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?

for me it was sufficient to to free up somespace on /boot drive

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?

Free disk space was my issue.

I also had this occur on an upgrade to 12.04B2. It probably was a disk space issue, I removed the old kernel and reinstalled. It would help a lot if it was possible to have old kernels automatically deleted.

Can you describe what procedure is taken to "reinstall"? Simply running do-release-upgrade a second does nothing, so how do I ensure the installer goes back to clean up its mess?

If do-release-upgrade is don't doing anything the system has already proceed that far, that sources.list files are replaced and the packet manager is configured for new packages. Therefore just run "dpkg --configure -a" to continue with the installation.
