TL;DR: Dear Kali user, when you have a moment, check your /etc/apt/sources.list, and add non-free-firmware if ever it’s missing.
Programmatically speaking:
kali@kali:~$ sudo sed -i 's/non-free$/non-free non-free-firmware/' /etc/apt/sources.list


Long story now.
As you might know already, Kali Linux is a Debian-based Linux distribution. As such, it inherits a number of things from Debian, and in particular, the structure of the package repository.

Kali Linux users need to ensure their /etc/apt/sources.list configuration includes 'non-free-firmware,' a component necessary for firmware updates. This new repository component was introduced in Debian and adopted by Kali in version 2023.1. It allows users to update firmware using apt update commands effectively.
