Carlos Nihelton (@CarlosNihelton) - a bunch of warnings from our distro validation script that I feel should be looked at.

Ben Hillis (@benhillis) Thanks for the ping! Are those warnings acceptable until the upcoming release date? Specially those systemd units mentioned in the script, most likely they won't get removed, but rather masked in the images. Is that an acceptable fix? We'll also have a new image release of 24.04 today, with the same warnings.

🟡 Changes recommended

The Arm64 URL host change (cdimagescdimage) and an unmentioned Ubuntu 24.04 bump need to be confirmed/clarified to avoid broken downloads and reviewer surprise.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

distributions/DistributionInfo.json:26

  • Same as above: this Arm64 URL switches from cdimages.ubuntu.com to cdimage.ubuntu.com with the /releases/<version>/release/ path. Unless this host change was explicitly verified, it risks a broken URL and CI validation failure.
