在我的服务器上，从（和）内核升级后5.4.0-48-generic，未检测到板载 realtek 以太网卡。奇怪的是，虽然在具有相同主板、网卡修订版和 bios 版本的游戏平台上，使用相同的 ubuntu 内核 ( ) 运行 KDE Neon，它工作正常。5.4.0-525.4.0-515.4.0-52-generic

这次rmmod r8169 && modprobe r8169realtek 解决方法不起作用。
我应该提交错误还是在 Ubuntu Server 中发生了发行版网络配置更改，但在 KDE Neon 中没有发生？
编辑：附加信息
r8168-dkms如果我有机会再次关闭服务器，我也会尝试该软件包并使用结果更新问题。
