Docker pull throws missing signature key error

We are using docker with RHEL 7. When pulling the newest docker image 8319 we get the error “missing signature key”. I found a article in the Redhat support forum that this is related to the manifest type. I checked the types with "sudo podman image inspect " which shows that the new image has the manifest type “vnd.oci.image.manifest.v1”. Image 6865 has type “vnd.docker.distribution.manifest.v2”. Would it be possible to continue to offer the image in the previous format / manifest type?

Hum, interesting.

I did change the machine which makes the releases, but it still uses Docker Desktop. Do you know how to configure that?

It says the errer occurs when the image was built by buildah.

I don’t use buildah, I use Docker Desktop which uses buildx.

An unwanted export as oci format with buildx can also be the cause (see docker buildx build). I would be very happy if you could look at it again. With the new format I can unfortunately no longer use jitsi. I think that others also will be affected by this problem in the near future.

I don’t know what to look into, sorry. I literally used the same release script as last time. My guess is Docker has changed the default, but I don’t know what to change.
