Comment 5 for bug 800093

Like I've said. I've got APT configured and the Shell. I've got no problems on the shell,
except the export of http_proxy to root when using sudo.
So what I can do is "sudo -E apt-get update".
Else it won't work if I don't set the http_proxy variable explicitly for that session.
