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?

      Sorry, maybe I should have explained every single step I tried in the body of the original post. I didn’t, partly because there were just too many and partly because I forgot which methods I had tried and which pages I had visited. But that page is one I’ve seen already.

      It mentions to “blacklist” the module in a file that doesn’t exist. In fact, in a file that’s in a directory that doesn’t exist, which makes me very sceptical about the later claim that creating that file will fix it. /etc/modules-load.d exists, but not /etc/modules.d. I did already try the final suggestion to add that line to the end of /boot/firmware/cmdline.txt though. No luck.

      I think the fact that it’s 6 years old is probably a big part of the reason it didn’t help. Files and directories have moved around. The suggestions in that post are literally just “do this” without any underlying explanation of what it’s doing that could lend to further investigation of the more modern way to do it.
