I had installed docker in ubuntu 18 and now wants to remove everything for a clean install. Had used : sudo apt-get install docker.io

This stackoverflow thread (though not meant for my exact installation) has a part-solution: docker remove answer

The only problem is that it doesn't mention how to remove other remaining docker files after running find / -name '*docker*' . There are so many in my system! screenshot_1 after "find / -name docker " >> screenshot_2 after "find / -name docker "

Additionally, I am looking for simple, hassle-free steps to install opensourcePOS on ubuntu 18 (Local deploy) git osPOS . The ones on git and osPOS website are for advanced users I guess - they leave a lot of details. Any links?

Try:

sudo apt-get purge -y docker.io 

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

sudo apt-get autoclean

sudo rm -rf /var/lib/docker

sudo rm -rf /etc/docker

sudo rm /etc/apparmor.d/docker

sudo apt-get purge runc containerd docker.io

This is the command docker suggests to use if you want to remove docker. I used it in ubuntu 18

https://docs.docker.com/engine/install/ubuntu/#uninstall-docker-engine

sudo apt-get remove docker docker-engine docker.io containerd runc

  • You say that's the command docker suggests. In this case it would be a good idea to provide the link to support your answer. – st.huber Jan 13 '22 at 08:56
