如何解决 Ubuntu 20.04 上的 Wifi 驱动程序问题

Question

我在我的 ubuntu 20.04 版本中安装无线驱动程序时遇到问题，也面临与（Ubuntu 18.04）相同的问题。

我已经通过rtl8822be wifi 驱动程序 ubuntu 20.04 hp 15-da1009ne。

这些是我正在遵循的步骤：

git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
git checkout extended
sudo make install
sudo modprobe -r rtl8723de
sudo modprobe rtl8723de

但是在执行 时sudo make install，我收到此错误：

make -C /lib/modules/5.4.0-28-generic/build M=/home/username/rtlwifi_new modules
make[1]: Entering directory '/usr/src/linux-headers-5.4.0-28-generic'

make[1]: Leaving directory '/usr/src/linux-headers-5.4.0-28-generic'

的输出lspci -knn | grep Net -A3; rfkill list：

较新内核中的该源有问题，因此请改用它

sudo apt install dkms
cd
git clone https://github.com/smlinux/rtl8723de.git
sudo dkms add ./rtl8723de
sudo dkms install rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414

检查是否mokutil --sb-state需要禁用安全启动 重新启动
