apt/jammy

apt will refuse to install nvidia-driver-470-server if nvidia-driver-450-server is installed *and* out of date. I can reproduce this by disabling all but the jammy release pocket, installing the old n-d-450-s from there, and then enabling updates and trying to install n-v-470-s (where a new
n-d-450-s is available):

# libnvidia-gl-450-server has an update available
root at dannf-apt-jammy:/var/cache# apt install --dry-run libnvidia-gl-470-server -o Debug::pkgProblemResolver=yes

The following packages have unmet dependencies:
