title: What does 'the agent has no identities' mean?
body: <p>I succesfully followed <a href="https://help.github.com/articles/generating-ssh-keys/" rel="noreferrer">these instructions</a> from GitHub on how to generate SSH keys and my connection with GitHub is succesfull. </p>
  
  <p>But when I later want to check my SSH key following <a href="https://help.github.com/articles/keeping-your-ssh-keys-and-application-access-tokens-safe/" rel="noreferrer">these instructions</a> I don't get the SSH fingerprint I see in my GitHub SSH Keys setting page when I use <code>ssh-add -l</code>.</p>
  
  <p>Instead of the SSH key fingerprint I get the message <code>The agent has no identities.</code> Why? And what does it mean?</p>
