URLs: the file `/usr/lib/apt/methods/https`
should exist. If it doesn't, you need to install the package

apt-get update
apt-get install apt-transport-https
}
Then, add the Docker repository key to your local keychain.

Add the Docker repository to your apt sources list, update and install
the `lxc-docker` package.
*You may receive a warning that the package isn't trusted. Answer yes to
continue installation.*

To verify that everything has worked as expected:
$ sudo docker run -i -t ubuntu /bin/bash
Which should download the `ubuntu` image, and then start `bash` in a container.
## Ubuntu Precise 12.04 (LTS) (64-bit)
This installation path should work at all times.
