在 /etc/netplan/0...yaml 中设置静态 ip 后，暂时无法解决“mirrors.aliyun.com”错误

我在vmware player里有个vm，dhcp4:ture改成

 dhcp4: no
        addresses:
            - 192.168.134.127/24
        gateway4: 192.168.134.1
        nameservers:
            addresses: [127.0.0.53,192.168.134.1, 8.8.8.8, 1.1.1.1]

在/etc/netplan/00-installer-config.yaml

IP设置成功，但是服务器好像无法再访问网络了。

我明白了Temporary failure resolving 'mirrors.aliyun.com'。看来我的 DNS 有问题。如何解决？

更新输出sudo netplan --debug apply：

答案1

Netplan 对间距和缩进的要求非常严格。此外，您的 yaml 文件省略了渲染器。我建议您将文件编辑为：

network:
  version: 2
  renderer: networkd
  ethernets:
    ens33:
      addresses:
        - 192.168.134.127/24
      gateway4: 192.168.134.1
      nameservers:
        addresses: [192.168.134.1, 8.8.8.8, 1.1.1.1]

来源：/usr/share/doc/netplan/examples/static.yaml

接下来是：

sudo netplan generate
sudo netplan apply

你连接了吗？测试：

ping -c3 8.8.8.8
ping -c3 www.ubuntu.com
