+If you don't want to run the get.docker.io script and want to use packages instead, you can use the docker PPA. Here is how you use it. Replace step 5 with the following 3 steps.

+

+1. Add the custom package sources to your apt sources list. Copy and paste the following lines at once.

+

+.. code-block:: bash

+

+   $ sudo sh -c "echo 'deb http://ppa.launchpad.net/dotcloud/lxc-docker/ubuntu precise main' >> /etc/apt/sources.list"

+

+

+2. Update your sources. You will see a warning that GPG signatures cannot be verified.

+

+.. code-block:: bash

+

+   $ sudo apt-get update

+

+

+3. Now install it, you will see another warning that the package cannot be authenticated. Confirm install.

+

+.. code-block:: bash

+

+    $ apt-get install lxc-docker
