I think I know what is going on here. When you set the proxy settings in your Gnome Preferences, it does two different things:
- Sets the /system/http_proxy gconf keys
- Sets the $http_proxy environment variable.
It appears to be the second of these that is causing the problem (at least for me). If you do an "unset http_proxy" from the command line, and then do a "sudo update-manager" things work fine. There doesn't appear to be anything wrong with the content of the $http_proxy variable (i.e. http://<user>:<pass>@<proxy-server>:<port>/ ), so I can only assume that update manager isn't parsing it correctly.
