Docker Manifest Inspect Not working for Ubuntu Latest images

[HarishKVarada]

Description

I am trying to run docker manifest inspect against Ubuntu version 18.04 and 20.04 and both are failing with No Such Manifest : docker.io/library/ubuntu:. We check this each night to see if there is a new image. It's by checking the current manifest for a tag.

I see recently ubuntu has some updates in docker hub for few tags. A Month Ago and from then we're seeing this error on Ubuntu

Reproduce

docker manifest inspect ubuntu:18.04
no such manifest: docker.io/library/ubuntu:18.04

docker manifest inspect ubuntu:lunar-20230124.1
no such manifest: docker.io/library/ubuntu:lunar-20230124.1

docker manifest inspect ubuntu:20.04
no such manifest: docker.io/library/ubuntu:20.04

Expected behavior

docker manifest inspect ubuntu:lunar-20221216

"schemaVersion": 2,
"mediaType": "application/vnd.docker.distribution.manifest.list.v2+json",

I think this is because the images switched to use the OCI mediatype.

This should be fixed in docker 23.0 through docker/cli#3990

docker manifest inspect ubuntu:18.04
{
   "schemaVersion": 2,
   "mediaType": "application/vnd.oci.image.index.v1+json",
   "manifests": [
      {
         "mediaType": "application/vnd.oci.image.manifest.v1+json",
         "size": 424,
         "digest": "sha256:fdd3c9372c19afa928f99afde58f0f80a008ebb695a8c5ee37de5adb7feb46de",
         "platform": {
            "architecture": "amd64",
            "os": "linux"
         }
      },

if you cannot update to 23.0, but have buildx installed, you can use docker buildx imagetools inspect

buildx imagetools inspect ubuntu:18.04
Name:      docker.io/library/ubuntu:18.04
MediaType: application/vnd.oci.image.index.v1+json

Closing this one as this was fix in 23.0
