when I try to add a service to a zone as permanent I get

RT_TO_PERM_FAILED: zone 'FedoraWorkstation' : org.fedoraproject.FirewallD1.Exception: Backup of '/etc/firewalld/zones/FedoraWorkstation.xml' failed: [Errno 13] Permesso negato: '/etc/firewalld/zones/FedoraWorkstation.xml.old'

What does it mean??
