When I try to restart MySQL using restart mysql
I get
restart: Rejected send message, 1 matched rules;
type="method_call", sender=":1.7" (uid=1000 pid=18869 comm="restart mysql ")
interface="com.ubuntu.Upstart0_6.Job" member="Restart" error name="(unset)"
requested_reply="0" destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init")
What's going on? This is Ubuntu 12.10.
I only ever see messages like this if I forget to use a suitably privileged account. Try
or obtain a suitably privileged shell and run the command in that.
