hi, we are observing artifacts missing for the beta version. The older version 4426.1.0 contains flatcar-nvidia-drivers-570-open.gz.

https://update.release.flatcar-linux.net/amd64-usr/4459.1.0/ is returning 404. We are forced to pin to 4426.1.0 before this issue is fixed but worried that the older flatcar image will be rendered obsolete soon.

Yes, that's expected because the version isn't released yet, so it doesn't show up on flatcar.org/releases or in the update server, on beta.release or update.release

that's surprising because the beta image on gcp is already pulling 4459

@yuhuyoyo The release is in progress which is of multiple steps. To better track - In this tracking issue, when you notice the Announcements are marked as done. That means main steps of the releases are complete.

Should we check the order of the release to make sure that the image is not the default beta image to pull when the artifacts are not uploaded yet? As I mentioned in the comment above, the default beta image is already updated to 4459 with status READY. Also the older version is already marked as DEPRECATED while the release is not yet done.

thanks. any update on fixing the order of waiting for the artifact to be uploaded before having the os image ready? My VM creation are using the flatcar-beta family and that will pull the wrong version if there's a huge delay between the two steps.
