运行 Ubuntu 18.04

安全启动已禁用。

答案1

我很长时间以来都遇到过类似的错误，升级内核已经帮我解决了这个问题。
运行此命令以智能地升级内核及其所有依赖项：

sudo apt-get dist-upgrade

答案2

Intel Wireless-AC 9560 仍然存在此问题。到目前为止，还没有解决方案。我尝试了所有方法，从切换到旧内核到更新驱动程序。可以有一些解决方法：

  1. 使用外部 WiFi 适配器。
  2. 使用手机的 USB 网络共享功能。

答案3

我通过以下命令修复了这个问题： sudo apt install backport-iwlwifi-dkms

然后重新启动系统。

它应该可以工作，因为它重新安装了英特尔适配器。
