Ubuntu 22.04 docker 搬家后名称解析失败

搬家后，我无法连接到互联网（本地和外部），我的安装了 docker 和家庭助理的 ubuntu 服务器。我没有更改服务器内部的任何内容，只是离线了大约 2 个月。现在我在新家里安装了网络，当我连接时，服务器名称解析失败。

您可能会要求以下事项：

  • ping google.com
ping: google.com: Temporary failure in name resolution
  • ping 8.8.8.8
ping: connect: Network is unreachable
  • netplan 正在运行
network:
  renderer: networkd

      dhcp4: true
      dhcp6: true
