Hello! I’ve been through the rigamaroll with this and am honestly stumped. I have a raspberry pi that I installed pihole onto, and then installed docker. I kept getting the error: Using default tag: latest Error response from daemon: Get "https://registry-1.docker.io/v2/library/hello-world/manifests/sha256:c41088499908a59aae84b0a49c70e86f4731e588a737f1637e73c8c09d995654": dial tcp [2600:1f18:2148:bc02:22:27bd:19a8:870c]:443: connect: network is unreachable when trying to pull the hello-world or any other container. I’ve tried forcing IPv6 on the systemd level and all of that but nothing works. I just did a fresh install or Raspbian and still have the same problems. Has anyone been able to fix this? Thanks!
I’ve even tried setting it in the hosts file but that still does not help.
What about curl and nslookup? do those try to use ipv6 as well?
I never tried RPI so I have no exprience, but I don’t think the Docker dameon would resolv domains differently than anything on the host. I stopped recommending it, but when some people had similar issues, I did recommend temporarily set one of the ipv4 addresses of the registry in the hosts file, but it caused other issues later when that IP was not available anymore. So you can try temporarily, but don’t accept it as a solution.
