Title:
  Maverick->Natty upgrade fails: "Could not calculate the upgrade"

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

Bug description:
  Binary package hint: update-manager

  I attempted the upgrade a regulation 10.10 release (with all current
  updates)  to 11.04 using ubuntu-11.04-alternate-i386.iso. The install
  terminated abnormally with "cannot mark 'ubuntu-desktop' for upgrade."
  Pursuant to the suggestion about unofficial software, I used Synaptic
  to uninstall everything that wasn't marked with the Ubuntu logo (with
  the exception of cups-ppdc), and retried the installation, with
  identical results.

  /var/log/dist-update/ attached.
