I'm getting it, slowly but surely.
I got the kernel headers installed, now I'm getting a new error:;;;;;
Neither the '/lib/modules/22.214.171.124-desktop-2mnb/build/include/linux/version.h' nor the '/lib/modules/126.96.36.199-desktop-2mnb/build/include/generated/uapi/linux/version.h' kernel header file exists. The most likely reason for this is that the kernel source files in '/lib/modules/188.8.131.52-desktop-2mnb/build' have not been configured.
What do they mean by "configuring kernel source files?"
