Ubuntu Fredericton Key Signing Meeting

Ubuntu Fredericton will open the new year by holding a key signing meeting. We will meet at Reids Newsstand, across from Kings Place on King Street, at 7:00pm. Please ensure that you bring a government-issued photo ID and a piece of paper containing your name, your GPG key ID, and your GPG key fingerprint (found with gpg --fingerprint KEYID).

Before coming, be sure to send your key to the Ubuntu keyserver with the command gpg --keyserver keyserver.ubuntu.com --send-keys KEYID

Replace KEYID with the ID of your GPG key. You can find it by running gpg --list-secret-keys | grep sec in a Terminal window, it's the part after "1024D/". Alternatively, this command will print out only the key ID: gpg --list-secret-keys | grep sec | tail -n 1 | cut -d"/" -f2 | cut -d" " -f1

This key ID is also the one you should use when getting your fingerprint to bring with you.

To sign a GPG key from the command line, follow these steps (KEYID is the ID of the key you're signing):

  • Add the key to your keyring with the command gpg --keyserver keyserver.ubuntu.com --recv-keys KEYID
  • Verify the fingerprint of the key (found with gpg --fingerprint KEYID) with the fingerprint on paper. If it's different, DON'T SIGN THE KEY!
  • Begin the signing process with the command gpg --sign-key KEYID
    • If there are multiple email addresses on the key, you will be asked if you are ready to sign them all.
  • Confirm that you want to sign the key.
  • Choose the option that corresponds to how confident you are in the key's authenticity.
    • If you can't answer with "I have done very careful checking" at this point, you should consider why you are signing the key in the first place. By now, you should have carefully verified the identity of the user.
  • Finally, send the key back to the key server with the command gpg --keyserver keyserver.ubuntu.com --send-keys KEYID

Confused yet? No? Good. Hope to see all the Fredericton-area Ubuntu users there.
