Are you running a valid version of Docker? Should be 17.something.

I’m not surprised you’re having problems, that version of Docker predates a lot of changes in image formats and such. You’ll want to follow the Docker installation instructions to get your system onto an up-to-date and supported version.

Is there any guide on how to update docker to latest version? I am completely noob at this so need step by step guide.
