Arvados

In source:tools/ansible/roles/compute_nvidia/files/arvados-nvidia.pref we currently have these pins:

Package: cuda
Pin: version 12.6.*
Pin-Priority: 995

Package: src:libnvidia-container src:nvidia-container-toolkit
Pin: version 1.17.*
Pin-Priority: 995

Package: cuda-drivers src:nvidia-graphics-drivers
Pin: version 560.*
Pin-Priority: 995

They don't work on Debian 12:

The following packages have unmet dependencies:
 nvidia-open : Depends: nvidia-kernel-open-dkms (>= 570.124.06) but it is not going to be installed
               Depends: nvidia-driver (>= 570.124.06) but it is not going to be installed
               Depends: nvidia-driver-cuda (>= 570.124.06) but it is not going to be installed
 nvidia-open-560 : Depends: nvidia-kernel-open-dkms (>= 560.35.05) but it is not going to be installed
                   Depends: nvidia-kernel-open-dkms (< 561) but it is not going to be installed
                   Depends: nvidia-driver (>= 560.35.05) but it is not going to be installed
                   Depends: nvidia-driver (< 561) but it is not going to be installed
                   Depends: libxnvctrl-dev (< 561) but 570.124.06-1 is to be installed

                   Depends: nvidia-settings (< 561) but 570.124.06-1 is to be installed

It looks like this might be resolvable by just pinning more nvidia packages. This output makes it look like some packages are unpinned and want to be the latest version 570 while others are pinned to 560 and those two sets can't be reconciled.
