Error while updating to new version

While updating to new version I got following error . Can anyone help ?

Sorry, user frappe is not allowed to execute ‘/usr/bin/supervisorctl status’ as root on trademode.

Did you install ERPNext using root account?
You can run bench update and then sudo supervisorctl restart
