Unable to push image to docker.pkg.github.com

[avgur]

Error occurred while trying to push built image into docker.pkg.github.com

Behaviour

When using 'push' option with docker.pkg.github.com error occured, in the same time it is still possible to build with 'load' option and then manually push each tag into docker.pkg.github.com

Steps to reproduce this issue

1. prepeare any dockerfile
2. use docker/build-push-action@v2 with 'push: true' option and tags prefixed with 'docker.pkg.github.com' f.e. 'tags: docker.pkg.github.com/repo/imagename:latest'
3. run action

Expected behaviour

image pushed into repository

Actual behaviour

action fails with an error:

failed to solve: rpc error: code = Unknown desc = failed commit on ref "layer-sha256:4766...": invalid content digest in response: invalid checksum digest format

Configuration

          DOCKER_TAGS="${DOCKER_IMAGE}:latest,${DOCKER_IMAGE}:1.0.0"
          echo ::set-output name=docker_registry::${DOCKER_REGISTRY}
          echo ::set-output name=docker_tags::${DOCKER_TAGS}

        uses: docker/login-action@v1 
        with:

          username: ${{ github.actor }}
          password: ${{ secrets.GITHUB_TOKEN }}
      -
        name: Build final image and push
        uses: docker/build-push-action@v2

In case local repository usage (like proposed in test documentation) everything works like a charm. In the time in case i will try to use "load: true" option (that way i have to switch 'push:false') i will also be able to push my images using normal docker push command

In case of several tags current error:
failed to solve: rpc error: code = Unknown desc = failed commit on ref "config-sha256:8a7a...": invalid content digest in response: invalid checksum digest format

In case of single tag the error:
failed to solve: rpc error: code = Unknown desc = failed commit on ref "layer-sha256:9045...": no response

@avgur This is a common issue (#127) with the deprecated GitHub Packages Docker Registry (aka docker.pkg.github.com). I suggest to migrate to GitHub Container Registry instead.

Is there a solution to this problem available for people using GitHub Enterprise Server?
They didn't manage to release the improved container registry so far...

[ygini]

@Fantaztig same issue here, did you find a solution?

We are GH Enterprise Server new users and moving our workflow from open GH to it, and stuck in a simple docker creation image process…

@crazy-max same issue here. Is there a solution for those of us on GitHub Enterprise Server?
