Just tried to install docker on my Ubuntu 16.04, and I get the error below. Any suggestions what is wrong and how to fix it?

Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

invoke-rc.d: initscript docker, action "start" failed.

$ sudo apt-get install -y docker-ce

On this same machine, I have a Linux Mint 17.3 installation on which docker worked just fine. Using same home directory as before on LM17.3.

Here are some specs:

Hi you might want to use journalctl to see exactly what is going wrong.

Use it like this:

# journalctl -u docker.service

To view logs and see what exactly went wrong.

Tip: use the --since flag to filter your search.

For more information on journalctl see this page.

It works now. It appears that docker-ce was installed all along and that it failed because I tried to install it again. Very odd. Normally, if you try to install a package that is already installed, you get something like this:

$ sudo apt install mypackage

Reading package lists... Done

Building dependency tree

Reading state information... Done

mypackage is already the newest version (5.7.19-0ubuntu0.16.04.1).

0 upgraded, 0 newly installed, 0 to remove and 27 not upgraded.

Perhaps the problem was that I had added different repos to /etc/apt/sources.list based on the different tutorials I followed. Embarrassing that I hadn't noticed that the service was running in the background all along and working just fine .. :/

Based on this link I used the following steps

• wipe /var/lib/docker (rm -rf /var/lib/docker) this will remove all existing containers and images.




• edit /etc/default/docker file and add the option:
  DOCKER_OPTS="-s overlay"

then

systemctl restart docker.service

For me, I get this error.

Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

Finally, I fixed the error in the /etc/docker/daemon.json by adding a missing comma before registry-mirrors

{

    "runtimes": {

        "nvidia": {

            "path": "/usr/bin/nvidia-container-runtime",

            "runtimeArgs": 

        }

    }    



    # I forget to add a comma , here !!!!!!!

    "registry-mirrors": ["https://docker.mirrors.ustc.edu.cn"]

}

After I added the comma and restarted docker with systemctl restart docker, I solved the issue.
