It would seem you have two or more services adding an lp group then. 
Or one service and a manually defined one.

Same problem here; you're probably adding an nginx group twice in some
way.  This is especially concerning, given that it's groups twice – for
some reason nothing is adding additional users or else that check would
have been triggered first.

I would have preferred, if you could instead have demoted it to a
warning.  I understand, that stuff suddenly breaking can be
frustrating, but I doubt the configurations you're using are fine.
