I installed Docker on Ubuntu a while back but when I tried to remove, the Docker still exists in the system. I followed this https://stackoverflow.com/a/31313851/2340159 but did

    Probably your problem is that for Docker that has been installed from default Ubuntu repository, the package name is docker.io

    Or package name may be something like docker-ce. Try running

    dpkg -l | grep -i docker
    

    to identify what installed package you have

    So you need to change package name in commands from https://stackoverflow.com/a/31313851/2340159 to match package name. For example, for docker.io it would be:

    sudo apt-get purge -y docker.io
    sudo apt-get autoremove -y --purge docker.io
    sudo apt-get autoclean
    

    It adds:

    The above commands will not remove images, containers, volumes, or user created configuration files on your host. If you wish to delete all images, containers, and volumes run the following command:

    sudo rm -rf /var/lib/docker
    

    Remove docker from apparmor.d:

    sudo rm /etc/apparmor.d/docker
    

    Remove docker group:

    sudo groupdel docker

    sudo rm -rf /var/lib/docker
    sudo apt-get autoclean
    sudo apt-get update

    Apparently, the system I was using had the docker-ce not Docker. Thus, running below command did the trick.

    sudo apt-get purge docker-ce

    sudo rm -rf /var/lib/docker

    hope it helps

    @miyuru. As suggested by him run all the steps.

    Ubuntu version 16.04

    Still when I ran docker --version it was returning a version. So to uninstall it completely

    Again run the dpkg -l | grep -i docker which will list package still there in system.

    For example:

    ii  docker-ce-cli      5:19.03.6~3-0~ubuntu-xenial               
    amd64        Docker CLI: the open-source application container engine
    

    Now remove them as show below :

    sudo apt-get purge -y docker-ce-cli
    
    sudo apt-get autoremove -y --purge docker-ce-cli
    
    sudo apt-get autoclean
    

    Hope this will resolve it, as it did in my case.
