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'
