在Ubuntu20.04.2上“sudo apt升级”之后，没有WiFi、以太网或GPU

Question

我使用20.04.2已经有一段时间了，没有任何问题。我运行'sudo apt更新‘，'sudo apt升级’，然后'sudo apt自动删除‘升级一些软件包，然后重新启动。

现在存在一些问题。我的WiFi和以太网设置没有出现在“设置”中。我没有互联网连接。

我的GT 1030 GPU不再显示在“关于”部分的设置。它显示为‘llvm管道(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的专用驱动程序就会出现并被选中。

这些可能是单独的问题或相关的。我没有把握。

我挖掘了一些可能的解决方案，但没有任何运气。

我进入了我的‘/etc/netplan/01-网络管理器-all.yaml’文件，这是存在的内容：

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

看来我的网络计划设置已经默认了。对如何解决这个问题有什么想法吗？

Answer 1

过去几天(在内核升级之后)，我遇到了同样的问题，在Ubuntu存储库中安装了r8168-dkms模块，尝试了各种复杂的修复方法。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进行传输：

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

这是用于may 8111/8168/8411 PCI千兆以太网控制器，特别是您的QCA9565 / AR9565无线网络适配器可能还有另一个可用的。
