ssh-rsa signature method on the target server.
Manual connection attempt from the target server to the source with enabled debug returns the following output:
# ssh -vvv -i .ssh/id_rsa_migration firstname.lastname@example.org
debug1: send_pubkey_test: no mutual signature algorithm
debug2: we did not send a packet, disable method
Connect to the target server via SSH.
Enable the algorithm by executing the command below:
# printf "\nPubkeyAcceptedKeyTypes +ssh-rsa\n" >> /etc/ssh/ssh_config
