buildah: buildah image - podman pull: unsupported docker v2s2 media type: ""

I followed the buildah tutorial for building an image and pushed the image to my local Nexus v3.22 artifactory - like this:

buildah push --tls-verify=false silent1:8082/alpine-basic docker://silent1:8083/uwe/alpine-basic:latest

The image is visible in Nexus artifactory.

When I now go and remove the image locally and try to pull the image from Nexus

podman pull silent1:8082/uwe/alpine-basic:latest

I get following error:

podman pull silent1:8082/uwe/alpine-basic:latest Trying to pull silent1:8082/uwe/alpine-basic:latest… unsupported docker v2s2 media type: “” Error: error pulling image “silent1:8082/uwe/alpine-basic:latest”: unable to pull silent1:8082/uwe/alpine-basic:latest: unable to pull image: Error initializing image from source docker://silent1:8082/uwe/alpine-basic:latest: unsupported docker v2s2 media type: “”

Note: that I can pull images from docker hub using podman and through Nexus like this without a problem: podman pull silent1:8082/httpd:2.4-alpine

Steps to reproduce the issue:

1. follow Buildah tutorial 1
2. mycontainer=$(buildah from alpine)
3. buildah run $mycontainer – apk --no-cache add bash
4. buildah config --created-by “uwe” $mycontainer
5. buildah config --author “also uwe” $mycontainer
6. buildah config --label name=“alpine-basic” $mycontainer
7. buildah commit $mycontainer silent1:8082/alpine-basic
8. buildah push --tls-verify=false silent1:8082/alpine-basic docker://silent1:8083/uwe/alpine-basic:latest
9. podman pull silent1:8082/uwe/alpine-basic:latest

Describe the results you received: podman pull command result is indicating a unsupported docker v2s2 media type: “”

Describe the results you expected: podman would pull the existing image from local Nexus artifactory
