   hello,
   i have resolved the previous issue. Now I'm able to start correctly Superset but i have still problem with Celery worker when i run this command to start the service as per documentation:
   celery worker --app=superset.tasks.celery_app:app --pool=prefork -O fair -c 4
   
   This is the error that i get (it seems is not able to connect to my postgresql db but the connection works well when  itry to use trhe same in Superset web portal)
   
   (env4) matteo@mbalzarotti-NB:~/superset$ celery worker --app=superset.tasks.celery_app:app --pool=prefork -O fair -c 4
