title: Remove Docker on ubuntu 18
body: <p>I had installed docker in ubuntu 18 and now wants to remove everything for a clean install. Had used :   <code>sudo apt-get install docker.io</code></p>
  
  <p>This stackoverflow thread (though not meant for my exact installation) has a part-solution: <a href="https://stackoverflow.com/questions/31313497/how-to-remove-docker-installed-using-wget?answertab=active#tab-top">docker remove answer </a></p>
  
  <p>The only problem is that it doesn't mention how to remove other remaining docker files after running <code>find / -name '*docker*'</code> . There are so many in my system!   <a href="https://i.stack.imgur.com/1GVR5.png" rel="nofollow noreferrer">screenshot_1 after "find / -name <strong>docker</strong> "</a>  >> <a href="https://i.stack.imgur.com/XYJXI.png" rel="nofollow noreferrer">screenshot_2 after "find / -name <strong>docker</strong> "</a></p>
  
  <p>Additionally, I am looking for simple, hassle-free steps to install opensourcePOS on ubuntu 18 (Local deploy) <a href="https://github.com/opensourcepos/opensourcepos" rel="nofollow noreferrer">git osPOS</a> . The ones on git and osPOS website are for advanced users I guess - they leave a lot of details. Any links? </p>
