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

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
