Which means that your local Computer system would not recognize the remote host. This will likely transpire the first time you connect with a whole new host. Form Certainly and push ENTER to carry on.

If you have saved the SSH essential with a different title other than id_rsa to avoid wasting it to another area, use the subsequent format.
