Container engine initialization error: ('Check if docker is running on the host.', DockerException("Error while fetching server API version: ('Connection aborted.', FileNotFoundError(2, 'No such file or directory'))"))
Unable to find image 'xeus-clang-repl:latest' locally
docker: Error response from daemon: pull access denied for xeus-clang-repl, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
See 'docker run --help'.

Can't find it on dockerhub nor here as a package.

Note, maybe I need to build the image locally first (which is fine) but then the README should be updated...

I will look at this as part of PR #77 , when refining my Dockerfile and updating the README
