Ubuntu 18.10 上的 Wifi 被 KO

apt 升级后，我的 WiFi 停止工作。网络属性面板中没有显示 WiFi 部分。

sudo lspci -v这是我的 WiFi的结果：

以下是对 sudo modprobe r8822be 的响应

[sudo] Mot de passe de romain : 
modprobe: ERROR: could not insert 'r8822be': Operation not permitted

以下是 grep -r r8822be /lib/modules 的结果

知道如何才能让我的 WiFi 卡重新运行吗？

答案1

正如 chili555 所说，该错误报告在此处：bugs.launchpad.net/ubuntu/+source/linux/+bug/1806472

在等待真正的错误修复时，禁用 BIOS 中的安全启动是解决方法。
