## This instruction from the official website will install the latest release of docker.
# Uninstall old versions
# Older versions of Docker were called docker, docker.io, or docker-engine. If these are installed, uninstall them:
sudo apt remove docker docker-engine docker.io containerd runc
# Install using the repository
sudo apt update
sudo apt-get install ca-certificates curl gnupg lsb-release
# Add Docker’s official GPG key:
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
# Set up the repository
