Ubuntu and updating Docker

Question

I am trying to run the latest stable version of docker and docker-compose.

I am following the instructions on https://docs.docker.com/engine/installation/linux/ubuntulinux/

Apparently the current version of docker-compose is 1.7.

Yet, after running through the documentation, installing docker-engine, I then get:

$ docker-compose --version
docker-compose version: 1.4.0

And

$ docker --version
Docker version 1.11.1, build 5604cbe

When I try to update it, I get the following:

$ sudo apt-get upgrade docker-engine
Reading package lists... Done
Building dependency tree      
Reading state information... Done
Calculating upgrade... docker-engine is already the newest version.
Done

$ docker-compose -v

The program 'docker-compose' is currently not installed. You can install it by typing:

sudo apt-get install docker-compose
anton@Charles:~$ sudo apt-get install docker-compose

docker-compose is already the newest version.

How do I update docker?

Answer 1

Try this

sudo sh -c "wget -qO- https://get.docker.io/gpg | apt-key add -"
sudo sh -c "echo deb http://get.docker.io/ubuntu docker main\ > /etc/apt/sources.list.d/docker.list"
sudo aptitude update
sudo aptitude install lxc-docker

If this is not working, lets do it via third party :

$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9
$ sudo sh -c "echo deb https://get.docker.io/ubuntu docker main > /etc/apt/sources.list.d/docker.list"
$ sudo apt-get update
$ sudo apt-get install lxc-docker
