cfg80211: failed to load regulatory.db

[dolivas27]

Hi guys and gals,

I have this error on boot and I don't think I had it before updating to 8.1 but I am not sure?

From my reading it has to do with the wireless driver but I am not using any wireless cards on the system.

If you know how to fix it or have link on how to fix it. That would be awesome.

Thanks,
Dean

801.11 is wifi. The error likely means you don't have the proper firmware installed.

Do you actually use the wireless? I don't think that error will affect anything else. If you want wifi to work maybe you need one of the non-free firmware packages. Which one depends on what wifi you have.

 

[dolivas27]

No I do not have wireless on the system. That's what strange about the error message.

Is there something I can remove or update?

My wifi-less server spits out a similar error and I never even noticed until now. I think that's about how important this is to fix. It tried to load some wifi stuff, you don't have wifi so it failed. Not a big deal.

I replaced these three files in the /usr/lib/firmware directory and no more errors.......

regulatory.bin
regulatory.db
regulatory.db.p7s

I got the files from here
https://git.kernel.org/pub/scm/linu.../?id=991b1ef696b7a034a5bf001cf31ab7735888c6e1

Hope this helps someone else........

Have an awesome day all............

On Debian 12(bookworm) I just installed the iw package and the error disappeared during the VM boot

Proxmox 8.3 just single line fix it.

apt install wireless-regdb

I am not sure why this even needed when i dont even have wireless card.

It isn't needed and nothing is broken if you aren't using wifi.

The kernel has a generic wifi layer that is separate from the card drivers and that's where the regulatory checks happen. If wifi is enabled in the kernel the generic layer gets loaded before the drivers. The fact that you have no wifi card is not yet known. A little bit of memory gets wasted in that case, the tradeoff being that the same kernel can support a wider variety of configurations.
