How to fix these missing firmwares

While doing Debian Stable upgrade today, I encountered following missing firmware warnings:

Code:
Setting up linux-image-5.10.0-12-amd64 (5.10.103-1) ...

Where is the problem and how can it be solved?

I think it's just a warning and not an error. I get that same type of warning for my wifi chip every time my kernel is updated. I don't worry about it, and my laptop works just fine.

The issue is that the firmware for the hardware is not installed, as it is a 'non-free' (non-opensource) package. In most cases it can be resolved by installing the firmware-linux & firmware-misc-nonfree packages by issuing the following command as root:

Quote:
apt-get install firmware-linux firmware-misc-nonfree
You might have to edit your /etc/apt/sources.list file and add 'non-free' (without the quotes) to the deb line. On my system this is what it looks like:

[quote]deb http://mirrors.kernel.org/debian/ unstable main non-free contrib [/code]

once you add it, run
Quote:
apt-get update
and then the command above to install.

These are actually warnings, not errors, so they might not apply to you. Here is the Debian wiki on firmware installation:
https://wiki.debian.org/Firmware

You also need to install the linux headers package if your system uses dkms to build extra modules.

I already have non-free mentioned in my sources.list:
Code:
deb http://deb.debian.org/debian/ bullseye main contrib non-free
deb-src http://deb.debian.org/debian/ bullseye main
deb http://security.debian.org/debian-security bullseye-security main
deb-src http://security.debian.org/debian-security bullseye-security main
deb http://deb.debian.org/debian/ bullseye-updates main
deb-src http://deb.debian.org/debian/ bullseye-updates main

Looks like the missing firmware relates to that card. But I suspect you only need some of those files.

Done.
Are these firmware packages also needed for desktops with Nvidia cards?
