Comment 1 for bug 43747

Do you run dapper? And use gnome-terminal? The gnome-terminal in dapper will automatically set the http_proxy environment. Apt-get uses this environment to get the proxy configuration. If you use a different terminal or no X at all, you have to configure it by different means (e.g. setting http_proxy by hand). There is little we can do about this because apt-get runs as the root user and it cant connect to the calling users gconf settings.
