Ubuntu 18.04 上的 netplan 配置失敗

編輯：這是我使用程式碼重命名介面後的精確情況。

這是我的網路計劃配置文件：

network:
 version: 2
 renderer: networkd
 ethernets:
   eno1:
     dhcp4: no
     dhcp6: no
     addresses: [192.168.1.93/24]
     gateway4: 192.168.1.91
     nameservers:
       addresses: [8.8.8.8, 8.8.4.4]

這是ip addr ls的輸出

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
   link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: rename2: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
   link/ether 00:1e:67:d6:33:24 brd ff:ff:ff:ff:ff:ff
3: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
  link/ether 00:1e:67:d6:33:25 brd ff:ff:ff:ff:ff:ff

當我執行sudo netplan –debug generate時，我得到以下輸出：

** (generate:1571): DEBUG: 00:08:01.444: Processing input file //etc/netplan/10-systemd-networkd-eth.yaml..
** (generate:1571): DEBUG: 00:08:01.444: starting new processing pass

** (generate:1571): DEBUG: 00:08:01.444: NetworkManager: definition eno1 is not for us (backend 1)

這是systemctl status systemd-networkd的輸出：

您已經ethMac在需要實際介面名稱的地方使用了文字字元串。將此更改為介面名稱，您可以通過執行命令來了解該名稱ip link。
