Comment 8 for bug 791944

I tried to manually start nmbd and I got the following:

carlos@kropotkin:samba$ sudo /etc/init.d/nmbd start
[sudo] password for carlos:
Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service nmbd start

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the start(8) utility, e.g. start nmbd
start: Job failed to start
carlos@kropotkin:samba$ service nmbd start
start: Rejected send message, 1 matched rules; type="method_call", sender=":1.53" (uid=1000 pid=5836 comm="start nmbd ") interface="com.ubuntu.Upstart0_6.Job" member="Start" error name="(unset)" requested_reply=0 destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init"))
carlos@kropotkin:samba$ start nmbd
start: Rejected send message, 1 matched rules; type="method_call", sender=":1.54" (uid=1000 pid=5849 comm="start nmbd ") interface="com.ubuntu.Upstart0_6.Job" member="Start" error name="(unset)" requested_reply=0 destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init"))

Does it help?
