title: How to remove docker which was install from binaries?
body: <p>I installed a docker-ce (version 18.06) in my Ubuntu 16.04 from binary which introduced in this page<a href="https://docs.docker.com/install/linux/docker-ce/binaries/" rel="nofollow noreferrer">1</a>.</p>
  
  <p>Now I want to remove it and reinstall docker-ce by apt.
  But I don't know how to remove it...
  I just know remove the things which I copy to /usr/bin..
  Any other thing should I do?</p>
  
  <p>Thanks!</p>
