我在安装过程中选择安装所有第三方驱动程序，并使用有线连接来更新软件，并检查其他驱动程序。仍然没有运气。
然后我在这里查看并发现一个类似的帖子，它似乎帮助了一位用户，但却未能解决我的问题。
发布的解决方案如下：
sudo apt update
sudo apt install build-essential git dkms
git clone https://github.com/tomaspinho/rtl8821ce.git
cd rtl8821ce
sudo ./dkms-install.sh
这对我来说很有效，我将在下面发布结果：

然而最初的用户说要跟进
sudo modprobe 8821ce
我无法运行此命令，目前我假设这就是我仍然没有 Wifi 驱动程序的原因。当我尝试运行它时，我得到了以下结果。
gino@DrHappy:~$ sudo modprobe 8821ce
[sudo] password for gino:
modprobe: ERROR: could not insert '8821ce': Operation not permitted
我试了几次以确保我没有输错密码，但还是没成功。下面我将发布原始问题的链接。我试图在那里添加这条评论，但由于在该特定主题上发帖需要声誉限制，因此不允许这样做。
联想 Thinkpad E480 - 在 Ubuntu 18.04 中未找到 Wifi 适配器
如果有人能告诉我哪里出了问题，或者有其他方法可以让我的 Wifi 正常工作，那就太好了。
答案1
我强烈地感觉到，问题在于此：https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1806472
“r8822be 模块别名完好无损，尝试对其进行 modprobe 或插入会导致“操作不允许”错误。”
我相信该错误也适用于其他几个 Realtek 模块。
请尝试禁用安全启动。
