tftpd command fail

tftpd-hpa-cmd-fail

vic@VictorAsus:~$ /etc/init.d/tftpd-hpa restart
Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service tftpd-hpa restart

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the stop(8) and then start(8) utilities,
e.g. stop tftpd-hpa ; start tftpd-hpa. The restart(8) utility is also available.
