You are trying to copy your SSH key to the server. For this you have to authenticate with the password (since your key is not already there), but password based authentication seems to be disabled on the server.

Your server states this:

Quote:

Permission denied (publickey,gssapi-keyex,gssapi-with-mic)

IIRC, if password based authentication would be allowed they would be the word password in this line. I might be wrong with this, but you can check by logging on to the server and have a look ath the file /etc/ssh/sshd_config and search for the line containing PasswordAuthentication. If it is set to yes or commented out (means beginning with a #-character) then password based authentication is allowed and this is not your problem.
