Answer 1

Please remove all old packages by using this command.

sudo apt-get remove docker*

I think you have to install repo by using following command.

if you use 64bit Ubuntu version

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

and after that

sudo apt-get update
sudo apt-get -y install docker.io

And confirm version by using

dom@dom-pc:~/web$ docker version
Client:
 Version:      1.12.6
 API version:  1.24
 Go version:   go1.7.4
 Git commit:   XXXXXXX
 Built:        Tue Mar 14 09:47:15 2017
 OS/Arch:      linux/amd64
Cannot connect to the Docker daemon. Is the docker daemon running on this host?

Answer 2

Follow these steps

• $ sudo apt-get remove docker docker-engine docker.io

• $ sudo apt-get update

• $ sudo apt-get install docker-ce

Answer 3

and if you wanted to upgrade to a later version

• ls /usr/bin | grep docker
  remove these files
  docker
  docker-containerd
  docker-containerd-ctr
  docker-containerd-shim
  dockerd
  docker-init
  docker-proxy
  docker-runc
  

• wget https://download.docker.com/linux/static/stable/x86_64/docker-17.06.1-ce.tgz (or whatever stable version you wanted)

• tar xfvz docker-17.06.1-ce.tgz

• cp docker/* /usr/bin/

• docker -v
  and you're done.
