Unable to locate package docker-ce

Hi, Im trying to install docker on a ubuntu 16.10.
I following the steps on https://store.docker.com/editions/community/docker-ce-server-ubuntu?tab=description.
I getting E: Unable to locate package docker-ce.
What can a noob do?

sorry im an idiot… need 16.0.4…

Hello,
you can try to download the .deb file on this page:
https://apt.dockerproject.org/repo/pool/testing/d/docker-engine/

Then install it with the command:
> sudo dpkg -i /path/to/package.deb

To make sure it was installed, just type:
> sudo docker run hello-world

and that’s it.
Hope it works!
