What that command tries to do is take the contents of the file containing the public portion of your SSH key pair, ~/.ssh/ and append it to the bottom of the file ~/.ssh/authorized_keys on your server.

So to add the new key, all you need to do is send the contents of ~/.ssh/ to the computer that already has access to the server and then copy and paste it into the ~/.ssh/authorized_keys on the server.

If you are using Debian or Ubuntu and you have your public key on GitHub, you can use the ssh-import-id on the server to do this automatically. Run:

ssh-import-id gh:github_username
