Title:
  "Could not calculate the upgrade " 11:04 to 11:10

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

Bug description:
  Hi all.

    I know that this type of "Could not calculate the upgrade" error has
  been reported before, but I have tried all solutions I could find in
  the old bug reports and on the forums, but to no avail. I am trying to
  go from 11.04 to 11.10 (with the final intent of bringing my system up
  to 12.04), but continually receive that error message while trying to
  do-release-upgrade. I am following proper upgrade protocol (I've
  updated all packages, fixed broken dependencies, and cleaned up my
  file system). I tried the solution mentioned here
  (http://ubuntuforums.org/showthread.php?t=1859338), but that doesn't
  work. I also purged my PPA's using PPA-purge, but that doesn't seem to
  help either.

  I'm attaching apt.log, and will attach main.log in a follow-up post.

  Any help/ideas will be greatly appreciated!
