No. It will complain in case of permissions problems, but this is not what
is happening here.

You can't start a driver multiple times for the same UPS. So if you ran
'upsdrvctl start', the script '/etc/init.d/nut start' (that will do so
also) will fail. You need to run 'upsdrvctl stop' first, if the driver is
running already for whatever reason.

You may want to upgrade to the latest stable version (2.0.5), although
this doesn't seem to be related to the problem you're having.

See above. This script attempts to start the UPS driver through
'upsdrvctl', but since it is already running, this fails. A well behaved
startup script would check for a successful startup of the driver and
would have terminated here. Why it isn't, is beyond me.
