Your client most probably is not configured to accept a password for the user root. This is ok for a configured system where you already have installed the public key, but will not allow you to do so using a password. You will have to o change the entry "PermitRootLogin" in /etc/sshd/ to yes o restart the sshd on the client o re-issue your ssh-copy-id o change back the entry "PermitRootLogin" in /etc/sshd/ to “prohibit-password” or “without-password” o restart sshd again. o test your connection. Or you may have to find another way to transfer id_rsa.pub. You may want to read the "PermitRootLogin" stanza in man sshd_config for further information. There seems to be a way to even limit logins with a public key to specific commands. This explicitly mentions backup purposes. All information above is from a fairly recent Debian system, so your mileage may vary depending on the OS and release you are using.
