我最近买了一台笔记本电脑（联想 Legion Pro 5）。在使用 Linux 20.04.6 LTS 双启动后，我的系统没有检测到任何 wifi 适配器。因此，我按照我在本论坛上找到的解决 realtek wifi 适配器无法找到 wifi 问题的常用步骤进行操作，如下所示：
sudo apt update
sudo apt -y install git build-essential linux-headers-generic
git clone https://github.com/lwfinger/rtw89.git
cd rtw89
make
sudo make install
sudo modprobe rtw89pci
即使按照以下步骤操作，我仍然收到以下错误：

有人能帮我解决这个问题吗？
