Well, isn't that just terrific. After updating my system (Kali GNU/Linux 2018.1 variation, to be specific), I got the following message on boot:
[ 14.146398] platform regulatory.0: firmware: failed to load regulatory.db (-2) [ 14.146477] firmware_class: See https://wiki.debian.org/Firmware for information about missing firmware
I have no idea what to do. I checked possible conflicted packages with
sudo apt-get dist-upgrade, but nothing seems to be out of place. The system itself works seemingly identically as prior to the reported error, in fact I'm typing this post on it right now. But I like to have my OS clean and in order, so I'm struggling to get rid of this error.
