  • Make sure you have installed the prerequisites for your Ubuntu version. Then, install Docker. – NIMISHAN Dec 15 '15 at 9:37
  • I already followed the steps in prerequisites sudo apt-get install linux-image-extra-$(uname -r) – praveen Dec 15 '15 at 9:43

    Have you created /etc/apt/sources.list.d/docker.list and add the correct deb entries for your Ubuntu? – Tung Tran Dec 15 '15 at 10:26
  • Thanks, earlier it is unable to create the /etc/apt/sources.list.d/docker.list after trying & trying finally it got created and successfully installed the docker in my machine.... thanks again.......! – praveen Dec 15 '15 at 11:10
  • Actually I am having the same issue although .../docker.list is correct avi@guest-Inspiron-1464:~$ cat /etc/apt/sources.list.d/docker.list deb apt.dockerproject.org/repo ubuntu-trusty main avi@guest-Inspiron-1464:~$ apt-cache policy docker-engine N: Unable to locate package docker-engine – igx Dec 15 '15 at 14:05

Try 'uname -a' and make sure you're running a 64-bit architecture:

Docker requires a 64-bit installation regardless of your Ubuntu version.



As mentioned in the comments, you have to

  1. find out your distribution name via lsb_release -c
  2. the file /etc/apt/sources.list.d/docker.list should have the following content (and nothing else): deb https://apt.dockerproject.org/repo ubuntu-VERSION-NAME main

In my case (Ubuntu 14.04 aka 'trusty') I added deb https://apt.dockerproject.org/repo ubuntu-trusty main

    Look at docs.docker.com/engine/installation/linux/ubuntulinux where there are detailed instructions on setting up apt and related keys to get docker. I had it installed via docker.io (the package maintained by ubuntu) which left me with an unresolved docker-engine package trying to install nvidia-docker. I had to uninstall and purge docker.io before getting docker-engine installed. – Caz Aug 26 '16 at 14:05

I fixed this issue by running apt-get update followed by apt-get install docker.io


I had other issues including "Unable" in Ubuntu 16.04. This is bash script to solve issues in my machine.


sudo apt update
sudo rm /var/lib/apt/lists/*
sudo rm /var/cache/apt/*.bin

VERSION-NAME=$(lsb_release -c)
y=$(echo $VERSION-NAME | awk '{print $2}')
echo $y
cd /etc/apt/sources.list.d
touch docker_test.list
echo "deb https://apt.dockerproject.org/repo ubuntu-$y main" > docker_test.list

sudo apt-get install linux-image-extra-$(uname -r) 
sudo apt-get update
sudo apt-get install docker.io

I had different issue when I had to uninstall Docker at the time. This is bash script (source) for my machine.

# For unistall in Ubuntu
sudo apt-get purge docker.io 
# This will erase all your container images
sudo rm -rf /var/lib/docker
# This will erase all docker configs
sudo rm -rf /etc/docker/
sudo apt-get purge docker.io
