cfg80211: failed to load regulatory.db

[mircolino]

Running PVE on an Intel NUC:

root@po:~# pveversion
pve-manager/9.2.11/f6997e698c7933ea (running kernel: 7.0.14-12-pve)

Checking dmesg for errors I get the following:

root@po:~# dmesg | grep -i "error"
[    4.775853] Bluetooth: HCI socket layer initialized
[    4.776105] Bluetooth: L2CAP socket layer initialized
[    4.776341] Bluetooth: SCO socket layer initialized
[    4.776843] faux_driver regulatory: Direct firmware load for regulatory.db failed with error -2
[    4.777104] cfg80211: failed to load regulatory.db

Since I don't want to disable bluetooth (which I need in a VM) I thought of installing the intel firmware.

root@po:~# apt install firmware-iwlwifi
The following package was automatically installed and is no longer required:

Continue? [Y/n]

Is it OK to continue? Why does it want to remove the packages proxmox-kernel-helper proxmox-default-kernel proxmox-kernel-7.0 proxmox-ve pve-firmware?

Is it OK to continue?

Not unless you want to break you Proxmox install.
