Grafana-Provisioning Permission denied error

0-07-17T19:39:35+0300 lvl=eror msg="A service failed" logger=server err="Failed to create 
provisioner: Failed to read dashboards config: could not parse provisioning config file: 
dashboards.yaml error: open /etc/grafana/provisioning/dashboards/dashboards.yaml: permission denied"
