I am experiencing something similar in the final Hardy Heron release.
When I run Update Manager from the applet it hangs just before asking
for my password. This has been happening ever since I upgraded (in-
place) to Heron from Gutsy. I have tried letting it run for hours and
killing it and
OK, I think I might have found it. Looking through this a

it appears as though the local machine's entry in /etc/hosts is not
quite right. My /etc/hosts was originally:
127.0.0.1 localhost
127.0.1.1 Udesktop.example.com
