Is there a work around for this ? After upgrading to Ubuntu 18.10 the hooks library changes so the corrected file works { "Control-agent": { "http-host": "172.16.26.249", "http-port": 8080, // Specify location of the files to which the Control Agent // should connect to forward commands to the DHCPv4 and DHCPv6 // server via unix domain socket.
