gitea: Registry: Error response from daemon: missing signature key after upgrade to 1.21.0

Description

Since the upgrade to 1.21.0 the docker image build succeed but the docker pull fails with

docker pull gitea.sikorski.cloud/rogersik/ansible:development
Error response from daemon: missing signature key

I suspect this is because of 1.21.0 because before the upgrade I din’t have this problem. I can’t

• Gitea 1.21.0
• using Act Runner on Kubernetes (with root rights)
• Minio as S3 storage

Test build locally with docker client

$ docker build . -t gitea.sikorski.cloud/rogersik/ansible:development
failed to fetch metadata: fork/exec /home/rsikorski/.docker/cli-plugins/docker-buildx: no such file or directory

DEPRECATED: The legacy builder is deprecated and will be removed in a future release.
            Install the buildx component to build images with BuildKit:

[rsikorski@ALIENWARE Ansible (feature/gitea-workflow-update)]$ docker pull gitea.sikorski.cloud/rogersik/ansible:development
Error response from daemon: missing signature key

I builded the image now on three different ways

• Gitea Act Runner: Kaniko
• Gitea Act Runner: Docker root
• locally on Ubuntu

I deleted the :development image and rebuild it the same error happens. When using an unused tag example test1 same error.

When downloading a ready image like alpine:latest

docker pull alpine:latest
docker tag alpine:latest gitea.sikorski.cloud/rogersik/ansible:development
docker push gitea.sikorski.cloud/rogersik/ansible:development
docker pull gitea.sikorski.cloud/rogersik/ansible:development
