名称解析暂时失败 - resolve.conf 指向 8.8.8.8 但仍不起作用

我已连接到互联网，但每当我 ping 一个网站时，我都会收到“名称解析暂时失败”的消息。

我已经尝试过以下操作：

  • 修改 /etc/resolv.conf 以包含nameserver 8.8.8.8和nameserver 8.8.4.4
  • 确保没有重定向 resolv.conf 的符号链接根据这个问题
  • 跑步sudo systemctl restart systemd-resolved.service
  • 重启我的电脑
  • 删除无线连接并重新连接

输出systemctl status systemd-resolved：

我还可以尝试什么？

我正在运行 Ubuntu 22.04.1。

答案1

尝试将/etc/resolv.conf文件设置为非存根版本。我在这方面取得了很大成功，尤其是当我的路由器提供 DHCP 时。

sudo rm /etc/resolv.conf 

sudo ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf
