body: <p>I followed the instructions on how to <a href="https://docs.docker.com/engine/installation/linux/docker-ce/ubuntu/#install-docker-ce-1" rel="noreferrer">install Docker CE for Ubuntu</a>.  After I setup the repository, and then ran <code>sudo apt-get update</code>, I got the following error:</p>
  
  <pre><code>Err:12 https://download.docker.com/linux/ubuntu artful Release

  Reading package lists... Done
  E: The repository 'https://download.docker.com/linux/ubuntu artful Release' does not have a Release file.
  N: Updating from such a repository can't be done securely, and is therefore disabled by default.
  N: See apt-secure(8) manpage for repository creation and user
