Unknown option: n

I tried to remove all instances of docker in order to complete a clean re-install but now I get a "Unknown option: n"
when I run docker Quickstart Terminal. And [docker ps] or [docker images] prints the following to the console: “Cannot connect to the Docker daemon. Is the docker daemon running on this host?”

Any ideas?


I get this same error… When clicking “Docker Quickstart” from the Launchpad, I get the following output.

              ## ## ##        ==

docker is configured to use the default machine with IP

Can you file an issue at https://github.com/docker/toolbox including the full output of the Quickstart please? Thanks

I finally resolved this error.

“head” was pointing to a different app then the one in /usr/bin/head
