I'm having the same problem after upgrading from 10.04 to 10.10. I've made the changes manually in my apt.conf file (It seems to take the proxy settings from the "System/Preferences/Network Proxy" when you apply it globally, but it doesn't set the authentication details?) However, this doesn't fix the problem. I can now run 'apt-get update' but clicking "check" in the update-manager still results in the 407 error.
