Dashboard Provisioning: failed to search for dashboards

I am getting an error from dashboard provisioning:

t=2018-10-10T09:29:20+0000 lvl=eror msg="failed to search for dashboards" logger=provisioning.dashboard type=file name=default error="lstat /var/lib/grafana/dashboards/interfaces.json: permission denied"

The directory and file are all set to 600 for user grafana. I’ve tested setting them all to 777 but still getting the same thing.

Not sure it matters, but it is being deployed by Chef.
