The openssh-server.postint does have code to create missing host keys:

host_keys_required() {
        hostkeys="$(get_config_option HostKey)"
        if [ "$hostkeys" ]; then
                echo "$hostkeys"
        else
                # No HostKey directives at all, so the server picks some
                # defaults depending on the setting of Protocol.
                protocol="$(get_config_option Protocol)"
                [ "$protocol" ] || protocol=1,2
                if echo "$protocol" | grep 1 >/dev/null; then
                        echo /etc/ssh/ssh_host_key
                fi
                if echo "$protocol" | grep 2 >/dev/null; then
                        echo /etc/ssh/ssh_host_rsa_key
                        echo /etc/ssh/ssh_host_dsa_key
                        echo /etc/ssh/ssh_host_ecdsa_key
                        echo /etc/ssh/ssh_host_ed25519_key
                fi
        fi
}

And running "dpkg-reconfigure openssh-server" fixes the issue.

Title:
  After Precise->Trusty, no /etc/ssh/ssh_host_ed25519_key is created

Status in “openssh” package in Ubuntu:
  New

Bug description:
  After upgrading a Precise (12.04.5) host to Trusty (14.04.1) the
  OpenSSH server keeps complaining about a missing host key:
  /etc/ssh/ssh_host_ed25519_key

  # grep -cF 'Could not load host key: /etc/ssh/ssh_host_ed25519_key' /var/log/auth.log
  203

  It seems the OpenSSH package doesn't run "ssh-keygen -A" in postinst.

  Workaround: run ssh-keygen -A as root:

  # ssh-keygen -A
  ssh-keygen: generating new host keys: RSA1 ED25519
