space requirement calculation seems to abort too early

[Kees Cook]

Binary package hint: update-manager

I was attempting upgrades in a kvm instance, but didn't have enough disk space.

I then noticed that the upgrade was requiring more and more space, even though I was freeing as much as it was asking for. Since the dist-upgrade logs are over-written (should they be set to append?), I don't have the prior history, but I started copying them off and comparing the space calculations. Note the "needs" value growing from 1377M to 1513M. This was more dramatic earlier when it claimed it only needed 600M, then 900M, then 1000M (roughly) in earlier attempts when there was very little disk space free (<200M, <400M, <800M roughly).

I should note, this is for a Gutsy -> Hardy upgrade.

[Launchpad Janitor (janitor)]

This bug was fixed in the package update-manager - 1:0.110.0

---------------
update-manager (1:0.110.0) jaunty; urgency=low

  * DistUpgrade/DistUpgradeCache.py:
    - take changes in update-initramfs into account when
      calculating the space requirements in /boot (LP: #287826)
    - when doing the space calculation, show the required space
      for each directory (if multiple need more space) LP: #219416
  * DistUpgrade/DevelReleaseAnnouncement:
    - updated for beta
  * UpdateManager/DistUpgradeFetcher.py:
    - set 5s timeout for the ReleaseNotes fetching (LP: #109397)
  * UpdateManager/UpdateManager.py:
    - pass the correct FetchProgress to the release-upgrade fetching
      code instead of the incorrect OpProgress
