Remove Docker on ubuntu 18

Question

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?
