System > Administration > Network. Under General tab set hostname to "http://hostname.com" then Close and reboot. Then add a key using apt-key like the Wine deb repository (http://www.winehq.org/site/download-deb). Result - GnuPG fails to add the key due to a temporary file creation problem (probably because of the // in the hostname).
