Docker Setup on Linux (Ubuntu)

Docker Docs Install Instructions: https://docs.docker.com/engine/install/ubuntu/#prerequisites

• Works for Ubuntu before 20.04
• If on 20.04 use below instructions in conjunction with the docs until a 20.04 version is released.

Ubuntu 20.04

Specifically the add-apt-repository command in the docs does not work because 20.04 focal release is not available. Follow these instructions: https://askubuntu.com/questions/1230189/how-to-install-docker-community-on-ubuntu-20-04-lts Instead of:

$ sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"

use

$ sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   bionic \
   stable"

Removing incorrect apt-repository

Use sudo add-apt-repository -r to remove: sudo add-apt-repository -r "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
