I managed to install docker according to docker's own tutorial. Then 4 months later I get an update from ubuntu to upgrade my docker. I thought, that sounds about right....why not??? So after the "upgrade" I now had two different versions of docker installed at the same time in two different locations and neither of them wanted to start. That was a great start to my day and cost me an hour or so to fix.
