sudo bash -c "curl -L https://github.com/docker/compose/releases/download/$COMPOSE_VERSION/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose"
sudo chmod +x /usr/local/bin/docker-compose
sudo bash -c "curl -L https://raw.githubusercontent.com/docker/compose/$COMPOSE_VERSION/contrib/completion/bash/docker-compose -o /etc/bash_completion.d/docker-compose"

Installing the latest version of Docker Compose can be done using Pip3:

$ sudo apt-get install python3-pip
$ sudo pip3 install docker-compose

$ docker-compose --version
docker-compose version 1.24.1, build 4667896

And then install this so docker login will actually work:

sudo apt-get install gnupg2 pass

Without it, you will likely get this error:

Error saving credentials: error storing credentials - err: exit status 1, out: `Cannot autolaunch D-Bus without X11 $DISPLAY`
