If you, like me, use Linux Mint 18 as OS and you want to install the latest version of Docker simply execute this commands:
sudo apt-get remove docker docker-engine docker.io
sudo apt-get update
sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable"
sudo apt-get update
sudo apt-get install docker-ce
sudo groupadd docker
sudo usermod -aG docker $USER
