I would like to build and run Docker containers on Ubuntu 16.04 LTS. How do I install Docker?

Docker comes in two flavours: The Comunity Edition (CE) and the Enterprise Edition (EE). See this question for the differences. Just take Docker CE if you don't know which to take.

There are two ways of installing it (thank you, Katu and Suor!). The official docker way is a bit more recent.

(A) Official Ubuntu Repositories

$ sudo apt-get install docker.io

In the past this way was discouraged as the docker package was super outdated. The universe sources are fairly recent now.

(B) Official Docker Way

The Ubuntu installation instructions list all you need in detail, but in most cases it boils down to:

(1) Set up the docker repository

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 $(lsb_release -cs) stable"

(2) Install Docker CE

sudo apt-get update
sudo apt-get install docker-ce

(3) Verify the installation

sudo docker run hello-world

The latest version can be found here. It was 18.06 in November 2018. This version is available in the sources from above, whereas the default Ubuntu package sources only contain Docker 1.5 (source). You can find changes in the docker release notes. Version 1.5 is so old that I could not find out how old it is.

  • How is this better than Ubuntu repo version?

    The official Docker sources are way more recent. See my updated comment. Nov 8, 2018 at 6:20

    @MartinThoma in my Ubuntu 16.04 the docker.io package is version 17.03.2 (November 2018)

  • @Katu Are you sure you use the default package sources? packages.ubuntu.com/xenial/docker.io says docker.io is in version 1.10 on Ubuntu 16.04 (xenial). edit: Ah, in universe sources there is a newer version! Nov 8, 2018 at 8:55

    Thank you, @Katu and Suor! I've adjusted my answer Nov 8, 2018 at 9:11

To install the Ubuntu repository version

sudo apt install docker.io

Check the version with

docker --version

You may still want to do the post-install steps. Thanks @wisbucky


Easiest way to install docker on Ubuntu using following command that you can get from the https://get.docker.com/

This script is meant for quick & easy install via:

$ curl -fsSL https://get.docker.com | sh


wget -qO- https://get.docker.com/ | sh

For test builds (ie. release candidates):

$ curl -fsSL https://test.docker.com | sh


 wget -qO- https://test.docker.com/ | sh

For rc build with experimental feature:

$ curl -fsSL https://experimental.docker.com | sh


 wget -qO- https://experimental.docker.com/ | sh

    piping directly into a shell is bad advice, no matter how commonplace it is.

    Really ? In typical situation you cant see source code at all, you just trust source of binary file (downloaded and executed) Jun 15, 2018 at 11:13

To install the community edition, add the GPG key

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Add the docker repository

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

sudo apt-get update

To make sure, you're going to install docker from Docker repo,

apt-cache policy docker-ce

Now install docker,

sudo apt-get install -y docker-ce

It would be running by default, but you can check the status

sudo systemctl status docker

BTW, for Linux Mint (which is based on ubuntu), need to change the release name by hand, after adding the repository.

Sub steps:

  • sudo vi /etc/apt/sources.list.d/additional-repositories.list
  • According to underling ubuntu versions:
    • Ubuntu 16.04
      Change sarah or other name, to xenial.
    • Ubuntu 18.04
      Change tara or other name, to bionic.

You can follow below steps to install docker-ce in Ubuntu -

  1. install the dependencies first

    sudo apt install apt-transport-https ca-certificates curl software-properties-common
  2. add the GPG key for the official Docker repository to the system:

    curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
  3. Add the Docker repository in sources.list.d to APT sources using below command -

    sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable edge"
  4. verify if you are able to install Docker from Docker repository

    apt-cache policy docker-ce
  5. Finally, install Docker CE package with below command

    sudo apt-get install -y docker-ce

Voila, you have installed Docker-CE. You can verify installation by checking the version of docker-ce installed

docker --version

For more detailed instructions, follow this tutorial


Debian installation.

  1. check your ubuntu code name

lsb_release -a | grep Code

Codename: xenial

  1. check your cpu architecture

lscpu | grep Arch


Finaly download your debian src. Go to https://download.docker.com/linux/ubuntu/dists/, choose your Ubuntu version, browse to pool/stable/ and choose amd64, armhf, ppc64el, or s390x. Download the .deb file for the Docker version you want to install.

sudo dpkg -i /path/to/package.deb

docker -v

Docker version 18.06.0-ce
