I’m currently trying to install Docker on my old Raspberry Pi (3 Model B+) to host some personal projects. When I run docker run hello-world, I get:

Unable to find image 'hello-world:latest' locally
docker: Error response from daemon: Get "https://registry-1.docker.io/v2/library/hello-world/manifests/sha256:ec153840d1e635ac434fab5e377081f17e0e15afab27beb3f726c3265039cfff": dial tcp [2600:1f18:2148:bc00:eff:d3ae:b836:fa07]:443: connect: network is unreachable

My Internet connection does not support IPv6 at all, which would explain why this error occurs. But how do I force docker-pull to only use IPv4?

    What version of Pi OS are you running?

    (we can move to DMs if you wish, it will be less polluting, or stay in the comment thread if you don’t feel safe in DMs)

      I’m happy to keep it public if only for the off chance that if we find a solution it might some day help someone else with the same issue. The thread’ll fall down in the rankings naturally over time anyway so I wouldn’t worry about polluting anything for people not actively seeking it out.

      I’m not 100% sure how to find the OS version, but uname -a outputs [...]6.12.25+rpt-rpi-v8[...]. /etc/os-release contains “Debian GNU/Linux 12 (bookworm)”. It should be whatever was latest as of a month or two ago when I installed the OS fresh.
