当渲染器联网时，netplan 正在尝试重新启动 NetworkManager

我熟悉旧式接口配置，但不熟悉 netplan。这是 Raspberry Pi 4 上的 Ubuntu Server 20.04 LTS。

我正在尝试配置一个静态 IP 地址，因此我按照在线示例进行操作，并且愚蠢地尝试使用 NetworkManager 作为渲染器（因为我复制/粘贴了）。 sudo netplan try正确地告诉我：Failed to start NetworkManager.service: Unit NetworkManager.service not found。我真傻。

所以我返回/etc/netplan/01-network-manager-all.yaml并将渲染器更改为 networkd。然后我运行sudo netplan try并再次得到：Failed to start NetworkManager.service: Unit NetworkManager.service not found。什么？

看一下这个：

$ ls /etc/netplan/
total 12K
drwxr-xr-x  2 root root 4.0K Jan 24 20:33 ./
drwxr-xr-x 93 root root 4.0K Jan 24 19:31 ../
-rw-r--r--  1 root root  226 Jan 24 20:31 01-network-manager-all.yaml

$ cat /etc/netplan/01-network-manager-all.yaml
network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      dhcp4: false
      addresses:
      - 10.11.12.15/24
      nameservers:
        addresses:
        - 8.8.8.8
        - 8.8.4.4
      gateway4: 10.11.12.1

$ sudo netplan try
Warning: Stopping systemd-networkd.service, but it can still be activated by:
  systemd-networkd.socket
Failed to start NetworkManager.service: Unit NetworkManager.service not found.

An error occurred: Command '['systemctl', 'start', 'NetworkManager.service']' returned non-zero exit status 5.

Reverting.

    raise CalledProcessError(retcode, cmd)
subprocess.CalledProcessError: Command '['systemctl', 'start', 'NetworkManager.service']' returned non-zero exit status 5.

当我将渲染器更改为网络时，为什么 netplan 仍尝试重新启动 NetworkManager？

遇到了同样的问题，意识到仅仅编辑 yaml 文件显然是不够的，您还必须运行：

sudo netplan generate && sudo netplan try

希望这对你也有用！
