error on installing virtualbox-additions-grsec
Following this guide https://wiki.alpinelinux.org/wiki/VirtualBox\_guest\_additions
I can not install virtualbox-additions-grsec, I get these errors:
depmod: can't open modules.builtin: no such file or directory
and some more, please see attached screenshot.
I guess that kernel headers are missing, but I do not know where to find them, I installed linux-virtgrsec-dev, but that still does not work out, something more is missing and I would really like to read it on that wiki page what should be installed. Please, please update that page. Please. Thanks.
