No module.dwarf installed after executing apt install dwarfdump, build-essential, linux-headers-generic, & make

[aryanadi-ic]

Hi all, I'm on Mac OS Sierra 10.12 using Ubuntu-20.04.2.0-desktop-amd64 inside a Virtual Box. I am getting module.mod module.mod.c module.o modules.order, instead of module.dwarf. I've been wondering why I am having this? Anybody has experienced this kind of issue/problem?
