I'm trying to use the CLEOS command line to vote, but as I follow the tutorial on developers.eos.io I'm running into problems pulling the Docker image.
So I've installed Docker on a fresh installation using Linux Mint Cinnamon. When I run docker --version it responds with Docker version 1.13.1 build.. then it shows a short alpha-numeric build code showing that it's installed.
So then I run docker pull eosio/eos-dev and it's coming back with an error saying Warning: failed to get default registry endpoint from daemon
Is this happening because the Mainnet hasn't be validated and opened to the public yet? If anyone can help me with this so I can vote using CLEOS, I'd appreciate it.
