我有一台基于 WM8880 SoC 的旧上网本（https://laptop.fossee.in/）用于运行 lubuntu 16.04（由福塞团队）通过 Uboot 引导加载程序相当好，有一天它说我可以升级到 18.04，所以我什至没有想到我做到了sudo apt-get dist-upgrade。
问题在那之后就开始了
wifi硬件不显示
背光键停止工作
sudo apt-get update或者install不起作用我最终得到
sudo apt-get update --fix-missing

从电路板图像中可以看出，我的 WiFi 卡是 Realtek 8152这里。我试图通过向团队请求原始固件来回滚，但他们没有，并且在线副本似乎是已删除。
该团队已经发布了内核源代码和一些其他工具这里
有什么方法可以让丢失的功能再次运行吗？
我正在考虑从源代码编译内核并尝试安装它？
可能出了什么问题？
