Wpa_supplicant won't install on Server 16

Update: no solution has been found, so far.

I want to test Big Blue Button (videoconferencing) but Server 16's kernel doesn't support my tablet's wifi adapter so I installed a newer kernel with the three .deb files (linux-headers, image and modules), rebooted, and then my card's recognized, but when I try to install wpa_supplicant.deb along with its dependencies that don't come with Server 16, I get a bunch of "package X will break package y" and "package x with break locales" errors, and I can't run Server 16 on a VM because I don't have enough RAM (until I get real server hardware). What can I do?
