在 Ubuntu 20.04.2 上执行“sudo apt upgrade”后没有 WiFi、以太网或 GPU

我已经使用 20.04.2 一段时间了，没有出现任何问题。我运行了“sudo apt update”、“sudo apt upgrade”，然后运行了“sudo apt autoremove”来升级一些软件包，然后重新启动。

现在出现了一些问题。我的 WiFi 和以太网设置未出现在“设置”中。我没有互联网连接。

我的 GT 1030 GPU 也不再显示在设置的“关于”部分中。它显示为“llvmpipe (LLVM 11.0.0., 256 位)”。但是，当我进入“软件和更新”并查看专有驱动程序时，我的 GT 1030 的专有驱动程序会显示出来并被选中。

这些可能是单独的问题，也可能是相关的。我不确定。

我花了一些时间寻找可能的解决方案，但没有任何收获。

我进入了我的“/etc/netplan/01-network-manager-all.yaml”文件，其中的内容如下：

# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager

看来我的 netplan 设置已经是默认设置了。有什么办法可以解决这个问题吗？

答案1

过去几天我遇到了同样的问题（在内核升级之后），尝试了各种复杂的修复方法后，最终在 Ubuntu 存储库中安装了 r8168-dkms 模块。由于 apt 显然不可用，您需要在另一台计算机上下载它并通过 USB 传输：

https://packages.ubuntu.com/focal/r8168-dkms

这是专门用于 RTL8111/8168/8411 PCI Express 千兆以太网控制器的，可能还有另一个适用于您的 QCA9565/AR9565 无线网络适配器的。
