Kernel headers are missing and you have to install them. Assuming you're running Raspian, read more here https://www.raspberrypi.org/documentation/linux/kernel/headers.md I suggest to install Arch: https://archlinuxarm.org/platforms/armv8/broadcom/raspberry-pi-4 and you will learn much about...

Do they match to the installed kernel? $ uname -r vs $ ls -la /lib/modules or $ dpkg -s raspberrypi-kernel | grep Version vs $ dpkg -s raspberrypi-kernel-headers | grep...

That's looking good. Now we have to check for the sub directories (build and/or source). Does one of them exists? $ ls -la /lib/modules/4.19.86-v7l+/

Unfortunately neither "build" nor "source" exists in your tree. So dkms isn't able to build the driver. For example my tree: drwxr-xr-x 21 zerobeat users 500 8. Dez 19:05 build...

looks that your installation is broken: https://github.com/raspberrypi/linux/issues/3279 https://github.com/respeaker/seeed-voicecard/issues/190

Take a look here: https://archlinuxarm.org/packages/armv7h/linux-raspberrypi4-headers Download the header package http://mirror.archlinuxarm.org/armv7h/core/linux-raspberrypi4-headers-4.19.86-1-armv7h.pkg.tar.xz Unpack and take a look inside the build tree. Now you can imagine what files you're missing: rwxr-xr-x 3 zerobeat...

You're on a wrong kernel version: 4.19.75-v7l+ Actual kernel is 4.19.86-v7l+ Please attach /var/lib/dkms/rtl8812au/5.6.4.2/build/make.log to see what's going on there. Or avoid complete dkms stuff. Compile driver and copy it...

dkms is a never ending story. If you not want to avoid it: https://raspberrypi.stackexchange.com/questions/93677/install-drivers-for-rtl8812au-for-raspibian-kernel-4-14-79-v7-or-4-14-79-87-v7 and/or https://github.com/aircrack-ng/rtl8812au/issues/408

Good to hear that. This chipset isn't bad and the driver has big potential.

And the Raspberry is a nice system, too. I'm running several of them, Pi 1: A+, B+, Zero wh and Zero. https://github.com/ZerBea/hcxdumptool/wiki/Penetration-testing-system-2
