Netplan 忽略嘗試並套用參數

Question

當我輸入以下命令時： netplan try 或 netplan apply netplan 不輸出任何內容。如果我再次嘗試啟動這些命令 netplan 輸出錯誤：

bind: address already in use
netplan: fatal error: cannot bind to port 2983, is another daemon running?, exiting.

因此 netplan 運行一些進程，就像我啟動服務一樣。

    {network dev}:
      dhcp4: no
      addresses: [{some one public IP}]
      gateway4: {XXX.XXX.XXX}.1
      nameservers:
        addresses: [8.8.8.8]
