尝试设置静态 IP 地址后，我的计算机无法识别网卡

安装 Ubuntu Server 20.xx 后，我更改了/etc/netplan/00-installer-config.yaml获取静态IP地址的内容：

network:
  ethernets:
    enp0s3:
      addresses: [192.168.1.17/24]
      gateway4: 192.168.1.1
      nameservers:
        addresses: [192.168.1.1]
  version: 2

但是当我执行：sudo netplan 申请好像我的网卡断开了，我无法检测到 IP 地址，当我卷曲-Ihttp://google.com我没有得到任何回应，并且以太网灯也没有闪烁。

更新：

我重新启动了电脑，但什么也没有改变！

有什么建议吗？

您的 .yaml 文件中的设备名称不正确。

将其用于静态地址：

network:
  version: 2
  renderer: networkd
  ethernets:
    enp3s0:
      addresses: [192.168.1.17/24]
      gateway4: 192.168.1.1
      nameservers:
        addresses: [192.168.1.1]
      optional: true

或者动态地址如下：

network:
  version: 2 
  renderer: networkd
  ethernets:
    enp3s0:
      dhcp4: true 
      optional: true

sudo netplan generate

sudo netplan apply

reboot
