package nvidia-driver-460 460.39-0ubuntu0.20.04.1 failed to install/upgrade: problèmes de dépendances - laissé non configuré

Problems with nvidia drivers : apparently "failed to install/upgrade: problèmes de dépendances - laissé non configuré".
The nvidia sound card is also not working (is it linked?) and I have no sound on my laptop.
