Taken from man ssh-keygen: `` -A For each of the key types (rsa1, rsa, dsa, *ecdsa* and ed25519) for which host keys do not exist, generate the host keys with the default key file path, an empty passphrase, default bits for the key type, and default comment. This is used by /etc/rc to generate new host keys.'' The default ecdsa key generated on my machine is ecdsa-sha2-nistp256. That's why I explicitly suggested (sudo) ssh-keygen -A.
