+    b. Obtain the dummy public key from any traditional OpenPGP Keyserver,
+    such as https://keyserver.ubuntu.com, and import the public key. The
+    fingerprint is 0xEDFFE248ECFACDE3C805906804A40D21DBB89B60. Note that, to
+    import this key, one must copy and paste the key in ASCII from the Keyserver
+    website to a file or console and use the command "gpg --import". Due to a
+    technical problem, Using "gpg --recv-key" or "gpg --search-keys" does not
