由于连接某些设备时出错，我在尝试将 bluez 和 bluez-cups 从 5.70 降级时使用了$dnf remove而不是匆忙，没有注意。$dnf downgrade
删除这些软件包并重新安装旧的 bluez 和 bluez-cups 后，我注意到我不再有以太网连接，而且我看不到任何 WiFi 网络。
dnf 删除了其他 3 个软件包：NetworkManager-bluetooth、bluedevil 和 bluez-obexd
我重新安装了 NetworkManager-bluetooth 软件包。我尝试过$dnf history undo并且$dnf history rollback
WiFi 或以太网没有问题，它们在同一台计算机上的 Windows 上运行良好。
有谁知道可能发生了什么？
