   On the desktop:

/etc/ssh/# ls
moduli                ssh_host_ecdsa_key        ssh_host_rsa_key.pub
ssh_config            ssh_host_ecdsa_key.pub    sshd_config
ssh_config.works      ssh_host_ed25519_key      sshd_config.works
ssh_host_dsa_key      ssh_host_ed25519_key.pub  supervise/
ssh_host_dsa_key.pub  ssh_host_rsa_key

   So the public keys are present here. And,

$ ls .ssh/
authorized_keys  config  id_ed25519  id_ed25519.pub  known_hosts

   I don't see why ssh is not finding the keys on the desktop.
