I also experienced the DistUpgradeViewGtk problem and solved it by installing python-vte. I was only able to figure this out because I debug Python code at work.
I'd think python-vte should be made a dependency of update-manager - that would solve this problem straightforwardly unless people ever download & run dist-upgrade.py directly! The update is now in progress, but I'm sure that any system hangs reported are a separate bug to the - quite simple to fix - python-vte bug. Hope this helps some - figured I'd report this so that other updaters to edgy will not have this problem. -- update-manager -c -d (can't find DistUpgradeViewGtk) https://launchpad.net/bugs/66376 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
