Possible missing firmware in debian

Question

I'm using Debian (Buster) with an Nvidia GT720 graphics card, and the nouveau module.

After running apt upgrade, I have this problem

What's this?

Answer 1

Firstly, make sure apt is installing the latest nonfree packages by adding them to your sources.list. There are plenty of posts elsewhere telling you how to do that.

I had a similar issue with the message: Possible missing firmware /lib/firmware/nvidia/gv100/acr/ucode_load.bin for module nouveau appearing when I updated Debian 10 on my Lenovo E530 laptop. I think there is a file missing from the current stable package. But I found this very useful page https://nouveau.freedesktop.org/CodeNames.html which tells you which software applies to which product. I believe this tells me that my GT630M graphics device requires the GF108 software and that the GV100 software only applies to the models NVIDIA Titan V and NVIDIA Quadro GV100. So I have ignored the error message.
