How do you install docker? I used, (https://docs.docker.com/engine/installation/linux/ubuntulinux/) at the end there is an optional commands in order to avoid using 'sudo' each time (this is not related to the problem you found)

Ok I got the messages... don't worry about this warning, the only thing that matters is that the docker installation finishes OK

zip_safe flag not set; analyzing archive contents...

Thanks
