Docker is easy to install from the Ubuntu repositories if you’re on an LTS release. I’m usually not though, so this is how I get the latest Docker onto my Ubuntu developer setup.

Download the latest from Docker – currently 18.10 Cosmic Cuttlefish

Install each file downloaded above e.g.

$ sudo dpkg -i containerd.io_1.2.2-1_amd64.deb
$ sudo dpkg -i docker-ce-cli_18.09.1~3-0~ubuntu-cosmic_amd64.deb
$ sudo dpkg -i docker-ce_18.09.1~3-0~ubuntu-cosmic_amd64.deb

Add your user to the docker group, if not done before (logout required)

$ sudo usermod -aG docker $USER

Verify the installation

$ docker --version

Repeat the steps to upgrade again.
