How does one get docker running on Ubuntu 16 and remove old installs?

I had taken a course on a training site that first suggested using sudo apt-get install docker.io or docker-io. The instructor then explained that this is an old method. So, then, without mentioning removing that version, he says to add a repo and use sudo apt-get update followed by sudo apt-get install docker lxc-docker. I saw the errors when I tried to see if it was running after this and to pull an image, not in that order - I mean I wouldn't try to pull if it wasn't running.

Anyway, I cannot seem to get it to start. I got this error instead Job for docker.service failed because the control process exited with error code. I setup a full gist to show the complete output. First I should note, that I do have docker installed in /usr/bin/docker and while I don't see a lxc-docker there are files in there that seem to relate to docker and start with lxc. The gist is at: https://gist.github.com/BruceMWhealton/0c6b84062b013d500089c5e22bf10462

Any advice would be greatly appreciated. Thanks, Bruce

The installation on Ubuntu docs have steps for this. Basically, add the current apt source:

deb https://apt.dockerproject.org/repo ubuntu-xenial main

Then update the cache and remove the old package:

sudo apt-get upgrade
sudo apt-get purge lxc-docker

Then you should be able to install the latest version - check with docker version and it will be (as of today) 1.12.1.
