Trustworthy Nvidia Container Toolkit Installation

After what seems like a series of longstanding issues with their certificate management (see the issues here), is there a trustworthy source to install the nvidia container toolkit? I am currently using their own repo (https://nvidia.github.io/libnvidia-container/stable/rpm/nvidia-container-toolkit.repo), but today I noticed this warning from dnf:

[6/6] Installing nvidia-container-toolk 100% |  26.0 MiB/s |   4.4 MiB |  00m00s
Warning: skipped OpenPGP checks for 4 packages from repository: nvidia-container-toolkit

Having the gpg-checks disabled seems like a somewhat bad idea.

Alternatively, is there another way to give containers GPU access besides using the nvctk as i.e. described here for podman?

There’s a COPR repo owned by the Fedora AI/ML Special Interest Group:

Thank you, I wasn’t aware of that.

apparently one can also install the nvidia-container-toolkit from the cuda repository:

sudo dnf config-manager addrepo --from-repofile https://developer.download.nvidia.com/compute/cuda/repos/fedora43/x86_64/cuda-fedora43.repo
sudo dnf install -y nvidia-container-toolkit
