This post assume that you know what docker is, if not please check the link here to know more about docker. Currently docker has two variants Docker-CE (Community Edition) and Docker-EE (Enterprise edition). In this post I am installing Docker-CE on to my Ubuntu 16.04 Xenial Desktop. We test the installation by simply running a hello world docker.
My Dell Vostro laptop comes with Ubuntu 14.04 LTS. Recently I updated my laptop with the updates provided by the OS. The new version of Linux kernel was also part of it. After installation it popped up a dialog with a check box “Disable UEFI secure boot”. I ignored to check this and clicked continue. UEFI secure boot was enabled in BIOS.
