Title:
  Lucid to Precise upgrade fails: release upgrader fails to start

Status in “update-manager” package in Ubuntu:
  Fix Released
Status in “update-manager” source package in Precise:
  Fix Released

Bug description:
  Just tried a Lucid to Precise Alpha 1 dist-upgrade by running "update-
  manager -d -c" and the Update Manager shows 12.04 available but
  clicking on Upgrade just causes the terminal to output:

  can't load DistUpgradeViewGtk (Unknown internal child: selection)
  can't load DistUpgradeViewGtk3 (No module named gi)
  can't load DistUpgradeViewKDE (coercing to Unicode: need string or buffer, tuple found)
  Must be connected to a terminal.

  I had not thought of even trying this earlier as I'd doubt any early
  testers would typically do that but I thought I should report it all
  the same.
