How can I install linux-headers for Volumio x86? I need them to install wl (Broadcom drivers) to get wi-fi working on an old MacBook laptop.
Volumio x86 comes with Linux kernel 3.18.25, and I can’t find any way to install that particular version of the the headers.
I’ve tried linux-headers-686, linux-headers-3.16.0-6, linux-headers-4.x (can’t remember the exact version) and linux-headers-amd64, but none of them will let me install wl (the installation is skipped as the 3.18.25 headers are missing).
