Install Docker Ubuntu

The Easiest way to install docker on ubuntu:

# 1. Remove any old conflicting versions (very important) 
sudo apt-get remove docker docker-engine docker.io containerd runc podman-docker
 
# 2. Official convenience script (still the simplest & reasonably safe method) 
curl -fsSL https://get.docker.com | sudo sh

After it finished:

# Add your user to docker group (so you don't need sudo every time)
sudo usermod -aG docker $USER
 
# Log out & log back in (or open new terminal)
newgrp docker
 
# Quick test
docker run --rm hello-world

If curl fails. do:

sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
