DEB822-STYLE format for Ubuntu 24.04+ apt repository instructions (.sources)

[berglh]

Ubuntu from 24.04 is now migrating to defaulting to the use of DEB822-STYLE sources.list.d format files, in particularly when you use add-apt-repository. There should be instructions of creating a /etc/apt/sources.list.d/nvidia-container-toolkit.sources file in the https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html website.

My current sources file looks like below, but it's also possible to embed the GPG key into the file as well, the key needs to be indented by one space below Signed-By.

Enabled: yes
Types: deb
URIs: https://nvidia.github.io/libnvidia-container/
Suites: stable
Components: main
Architectures: amd64
Signed-By: /etc/apt/keyrings/nvidia-container-toolkit-keyring.gpg

Or

Enabled: yes
Types: deb
URIs: https://nvidia.github.io/libnvidia-container/
Suites: stable
Components: main
Architectures: amd64
Signed-By: -----BEGIN PGP PUBLIC KEY BLOCK-----
 .
 ${ GPG KEY CONTENTS }
 -----END PGP PUBLIC KEY BLOCK-----

My source file looks like the above, however, I am receiving an error Error: The repository 'https://nvidia.github.io/libnvidia-container stable Release' does not have a Release file. . I'm currently on Ubuntu 24.10, but this method was previously working for me on Ubuntu 24.04. Either way, having some instructions for the new source file format would be beneficial. I'll see in the meantime if I can resolve my error.

I got this working with Ubuntu 24.10, but with a warning against the InRelease file.

Warning: Conflicting distribution: https://nvidia.github.io/libnvidia-container stable/deb/amd64/ InRelease (expected stable/deb/amd64/ but got stable)

The InRelease file looks like this:

Hash: SHA512

Architectures: amd64
Codename: stable
Components: main
Date: Fri, 27 Apr 2018 21:29:25 +0000
Description: NVIDIA container runtime library repository
Label: NVIDIA CORPORATION <[email protected]>
Origin: https://nvidia.github.io/libnvidia-container/stable
Version: 1.0

My guess is that the path provided using the fields below would match as opposed to the URI path in Suites, however, it expects the InRelease file in the stable directory I think and fails to discover the file if configured in this way. I got around this by specifying the full path in Suites and omitting Components and Architecture. A simple solution might be to update the InRelease file to change the Codename to "stable/deb/amd64/" but I'm unsure how this would impact legacy .list configurations.

Suites: stable
Components: deb
Architecture: $(ARCH)

Either of these are working for me:

Enabled: yes
Types: deb
URIs: https://nvidia.github.io/libnvidia-container
Suites: stable/deb/$(ARCH)/
Signed-By: /etc/apt/keyrings/nvidia-container-toolkit-keyring.gpg

Or, with the GPG key embeded in the .sources file.

Enabled: yes
Types: deb
URIs: https://nvidia.github.io/libnvidia-container
Suites: stable/deb/$(ARCH)/
