Unable to locate package docker-engine

Question

I'm trying to install docker on Ubuntu in vmware, unsuccessfully. These are the commands and errors I experience.

sudo apt-get update

sudo apt-get install docker-engine
Reading package lists... Done
Building dependency tree

E: Unable to locate package docker-engine

Solution 1

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

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

Solution 2

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

Solution 3

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

Make sure you have installed the prerequisites for your Ubuntu version. Then, install Docker.

I already followed the steps in prerequisites sudo apt-get install linux-image-extra-$(uname -r)

Have you created /etc/apt/sources.list.d/docker.list and add the correct deb entries for your Ubuntu?

[praveen]

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.......!

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

perform all the actions (commands) as root, otherwise it wont create properly -- once again follow the steps from starting in docs in docker site : docs.docker.com/engine/installation/ubuntulinux

I've added sources, also have tried to use Docker's shell script to install all automatically, but still got E: Unable to locate package docker-engine for all cases...

@praveen Did you call sudo apt-get update after modifying docker.list? That did the trick for me.

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.
