Title:
  Can't Connect to Open Network

Status in netplan:
  Fix Released
Status in netplan.io package in Ubuntu:
  Fix Released

Bug description:
  The man page states:

  access-points (mapping)

  ...

      password (scalar)
          Enable WPA2 authentication and set the passphrase for it. If not given, the network is assumed to be open. Other authentication modes are not currently supported. 

  If I configure Netplan this way:

    wifis:
      wlp1s0:
        dhcp4: yes
        access-points:
          "My Open Network":

  Upon "sudo netplan apply":

  Error in network definition //etc/netplan/01-netcfg.yaml line 16
  column 28: expected mapping

  If I configure Netplan this way:

    wifis:
      wlp1s0:
        dhcp4: yes
        access-points:
          "My Open Network":
            password:

  Syslog shows:

  Netplan will happily connect to any access-point that has a password.
