Comment 0 for bug 186465

I tried upgrading to Hardy using "update-manager -d". After checking for updates, I get a button to upgrade to 8.04, which I pressed. This brings up the distribution upgrade dialog, showing the various steps its going to do. This dialog shows the progress bar advancing a bit, and then it becomes totally unresponsive, not even repainting its own window.

The terminal shows

mbp@lithe% sudo update-manager -d
warning: could not initiate dbus

zsh: quit (core dumped) sudo update-manager -d
