Summary	0004697: platform regulatory.0: firmware: failed to load regulatory.db (-2) after update to kernel 4.15
Description	Looks like after i upgraded to the kernel 4.15 i started having this error at boot. Dig some digging and looks like it's been reported for several other distros as well. My own findings show that it could have something to do with my internal wi-fi card which is a broadcom. Before updating the kernel i was able to use the broadcom-sta-dkms driver instead of the b43 one. After upgrading the kernel to 4.15 the broadcom-sta-dkms driver does not work anymore and i was forced to go back to b43.
Steps To Reproduce	possibly any internal broadcom wireless card and a Kali linux version updated to the 4.15 kernel

The regulatory.db issue is described here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=892229 I have prepared an updated wireless-regdb package if you want to test it out: https://people.debian.org/~hertzog/packages/wireless-regdb_2017.12.23-1_amd64.deb But if you want to understand why broadcom-sta-dkms no longer works with your card, then you should probably try to provide more information like concrete error messages, logs, etc.

rhertzog 2018-04-13 21:05 administrator ~0009036	The package that I prepared is likely not working (kernel will likely complain that it can't verify the signature) but an updated (and fixed) one should land soonish in Debian unstable.

g0tmi1k 2018-10-30 11:14 administrator ~0009855	Due to the age of the OS (Kali Moto [v1], Kali Safi [v2], Kali Rolling 2016.x/2017.x/2018.1), these legacy versions are no longer supported. We will be closing this ticket due to inactivity. Please could you see if you are able to replicate this issue with the latest version of Kali Linux - https://www.kali.org/downloads/)? If you are still facing the same problem, feel free to re-open the ticket. If you choose to do this, could you provide more information to the issue you are facing, and also give information about your setup?
