I suggest you report a bug. Xenial is not ready and not stable.

I installed the Docker binary direct from Dockers website and not from apt-get and I get a similar error

docker pull ubuntu
Using default tag: latest

actually, I need to stop assuming its a xenial bug

its a docker daemon and permissions thing

sudo ./docker daemon -D

sudo docker pull fgrehm/devstep:v0.4.0

obviously running docker under sudo is bad form..

but it does indicate, its not xenial bugging out, its docker config

I had to install 1.10 version of Docker from binary on Xenial and it didnt create the docker group and so this was useful
