Ok so I got a bit further by running curl -sSL https://get.docker.com | sh which initially gave an error about the repos but running sudo apt-get update --allow-releaseinfo-change fixed that. this got me past the initial issue but the same thing happened at the docker-compose section so I ran sudo pip3 install docker-compose which then allowed the installation to complete but then I got the same error as this post so followed the advice and now when I run docker-compose up -d it runs without error but I get no webpage at myipaddress:8000
I wonder if it is even worth the effort, it’s just Kegberry seems so perfect for what I want it is a shame to give up.
