Hello,
I’m trying to install the driver for my Realtek RTL8812AU Wi-Fi adapter on DietPi, but I’m encountering some issues. I’m using a Raspberry Pi with kernel 6.1.21-v7+.
I downloaded the driver from this GitHub repository and extracted it into the rtl8812au folder. However, when I try to compile it with make, I get the following error:
make ARCH=arm CROSS_COMPILE= -C /lib/modules/6.1.21-v7+/build M=/home/dietpi/rtl8812au modules
make[1]: *** /lib/modules/6.1.21-v7+/build: No such file or directory. Stop.
make: *** [Makefile:1730: modules] Error 2

Steps to reproduce
Download the RTL8812AU driver from this GitHub repository.
Extract the driver folder to /home/dietpi/rtl8812au.
Run make inside the folder to compile the driver.
Expected behaviour
The driver should compile successfully and install the Realtek RTL8812AU Wi-Fi adapter.
Actual behaviour
Compilation fails with the error:
make ARCH=arm CROSS_COMPILE= -C /lib/modules/6.1.21-v7+/build M=/home/dietpi/rtl8812au modules
make[1]: *** /lib/modules/6.1.21-v7+/build: No such file or directory. Stop.
make: *** [Makefile:1730: modules] Error 2
Attempting to install kernel headers results in the following error:
E: Unable to locate package linux-headers-6.1.21-v7
E: Couldn’t find any package by glob ‘linux-headers-6.1.21-v7’
Extra details
Wi-Fi Adapter: Realtek RTL8812AU
Kernel Version: 6.1.21-v7+
Wi-Fi Adapter Manufacturer: MediaTek (Ralink Technology)
I’ve confirmed that the kernel headers are not available for the current kernel version, which seems to be preventing the driver from compiling.
