Removing those files manually is risky and not the recommended approach - the proper way is to follow the news article instructions (pacman -S --overwrite /usr/lib/firmware/nvidia/* linux-firmware) so the package manager can track everythng correctly.
I thought it was a residue of something that i tried to install and just removed it using,
sudo rm -rf /usr/lib/firmware/nvidia/ad103 /usr/lib/firmware/nvidia/ad104 /usr/lib/firmware/nvidia/ad106 /usr/lib/firmware/nvidia/ad107
But then it the update worked fine. I thought, my system don’t have NVIDIA, so it might not be necessary.
