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.

Just checking /var/log/dist-upgrade and the term.log is blank but I'm attaching the brief main.log.

Thanks for testing this that early. I can confirm this error and thus setting the status 'triaged'

This bug was fixed in the package update-manager - 1:0.154.6

update-manager (1:0.154.6) precise; urgency=low

  * DistUpgrade/DistUpgrade.ui:
    - remove <child internal-child="selection"> as this is not
      supported by the gtkbuilder in lucid and makes the release
      upgrader crash (LP: #898482)

then shouldn't that version of update-manager be backported to lucid since the orginal reporter was trying to upgrade lucid to precise instead of just putting it in precise

cpatrick08 - when you use update-manager -d it downloads the precise version of update-manager to use for the distribution upgrade so this only needs to be fixed in Precise. It would be helpful if you were to report a new bug about this issue since yours is different while it creates the same problem.

This bug has been reported on the Ubuntu ISO testing tracker.
