Docker: ERROR [internal] load metadata for docker.io

Question

On Windows 10, Docker Desktop (Docker Engine v20.10.17, WSL enabled and running properly) fails to docker build an image (that, btw, works properly on Debian 11) throwing following error:

docker build -t <image-name> .
[+] Building 2.3s (3/3) FINISHED
 => [internal] load build definition from Dockerfile                                0.1s

failed to solve with frontend dockerfile.v0: failed to create LLB definition: failed to authorize:
rpc error: code = Unknown desc = failed to fetch anonymous token: Get
"https://auth.docker.io/token?scope=repository%3Arocker%2Fr-base%3Apull&service=registry.docker.io":
dial tcp: lookup auth.docker.io: no such host

A similar case was answered here, although the solution doesn't apply in my case. Searching the web yielded several similar (but not identical) cases with different solutions (including a reinstall), which all failed to solve this.

Answer 1

In the end I found a (or the) solution in the Docker forum: in Docker Desktop, navigate to Settings > Docker Engine, change buildkit to false in the Docker daemon configuration file and then click "Apply & Restart".

{
  "builder": {
    "gc": {
      "defaultKeepStorage": "20GB",
      "enabled": true
    }
  },
  "experimental": false,
  "features": {
    "buildkit": false
  }
}

Answer 2

Solution:

sudo rm  ~/.docker/config.json 
Rerun restart
