The script was assembled using the official Docker docs:

• Get Docker Engine - Community for Ubuntu
• Install Docker Compose as a container
• Command-line completion

install-docker.sh

#!/bin/sh

set -o errexit
set -o nounset

IFS=$(printf '\n\t')

# Docker
sudo apt remove --yes docker docker-engine docker.io containerd runc || true
sudo apt update
sudo apt --yes --no-install-recommends install apt-transport-https ca-certificates
wget --quiet --output-document=- https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository --yes "deb [arch=$(dpkg --print-architecture)] https://download.docker.com/linux/ubuntu $(lsb_release --codename --short) stable"
sudo apt update
sudo apt --yes --no-install-recommends install docker-ce docker-ce-cli containerd.io
sudo usermod --append --groups docker "$USER"
sudo systemctl enable docker
printf '\nDocker installed successfully\n\n'

printf 'Waiting for Docker to start...\n\n'
sleep 5

# Docker Compose
sudo wget --output-document=/usr/local/bin/docker-compose "https://github.com/docker/compose/releases/download/$(wget --quiet --output-document=- https://api.github.com/repos/docker/compose/releases/latest | grep --perl-regexp --only-matching '"tag_name": "\K.*?(?=")')/run.sh"
sudo chmod +x /usr/local/bin/docker-compose
sudo wget --output-document=/etc/bash_completion.d/docker-compose "https://raw.githubusercontent.com/docker/compose/$(docker-compose version --short)/contrib/completion/bash/docker-compose"
printf '\nDocker Compose installed successfully\n\n'

Not work for Docker Compose v2

compose_release() {
  curl --silent "https://api.github.com/repos/docker/compose/releases/latest"   #@|
  grep -Po '"tag_name": "\K.*?(?=")'
}

if ! [ -x "$(command -v docker-compose)" ]; then
  curl -L https://github.com/docker/compose/releases/download/$(compose_release)/docker-compose-$(uname -s)-$(uname -m) \
  -o /usr/local/bin/docker-compose && chmo

Current script fails on docker compose

`Docker installed successfully

running compose version also returns permissions denied

docker-compose --version
-bash: /usr/local/bin/docker-compose: Permission denied

The link to run.sh seems broken

@decentraliser yes the link is broken, since the 2.x rework in GoLang the auto completion script was removed
I suggest we remove the auto completion install form the script
