Accordingly I received a mail in my GMail account (I had used GMail for registering in Launchpad), and I copied the PGP contents and pasted in the terminal in gpg command. This is the output I got,
user: "abc <email@example.com>"
4096-bit RSA key, ID ABCD1234, created 2012-06-15 (main key ID EFGH5678)
gpg: encrypted with 4096-bit RSA key, ID ABCD1234, created 2012-06-15
The gpg program is not exiting after this.
After this, the Guide just asks us to go and confirm the PGP key in the Launchpad page. But I don't see any such link there.
Am I doing something wrong here? How does running gpg on my computer inform launchpad if the key is valid or not?
