+       Update the local keyring with the keys of a key server
+       and removes from the keyring the archive keys which are no
+       longer valid. This requires an installed wget and an APT
+       build configured to have a server to fetch from. APT in
+       Debian does not support this command, but Ubuntu's APT
+       does.
