The preferred way to get a new key into the apt keyring is to tell
apt-key to fetch the key directly.  You must specify the key server to
use - this example uses the ubuntu keyserver):
  sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys AB9B66FD

This avoids the need to import the key into your own keyring (unless you
want a copy of that key in your personal keyring).  If you want a
reference copy of the key, then try
 gpg ---recv-keys AB9B66FD; gpg -a --export AB9B66FD | apt-key add -

If ~/.gnupg/gpg.conf doesn't list a keyserver, you will need to specify
the keyserver to the first gpg command, exactly as it is specified for
the apt-key adv operation.

The following commands fail because apt-key expects a file name for the
add operation to process (the '-' in the above sequence causes it to
read from the pipeline).

Hope this helps
