Public keys are missing on the source server, or a public key on the source and target server is not compatible.
Create the RSA Key Pair on a target server:
# ssh-keygen -t rsa -b 2048
Permissions for the private key should be 0600
Copy the public key from target to source server over ssh protocol:
# ssh-copy-id firstname.lastname@example.org
