This assumes that

you just created the server and nothing has been installed except the OS
you're logged in as root
you have a domain or subdomain you're installing opencart at

Update server

First things first, update the package repos and upgrade stuff

sudo apt update
sudo apt upgrade -y

Install systems requirements

Install server requirements (Apache, PHP and dependencies)

sudo apt install -y apache2 php php-curl php-gd php-zip certbot unzip

certbot is for SSL, and unzip is to extract opencart files, both we'll use later

Restart Apache after installing dependencies (otherwise they don't show up on the Opencart install page)

MySQL

sudo apt install mysql-server mysql-client

Now secure the MySQL installation by setting a root user password and other stuff

mysql_secure_installation # interactive

PhpMyAdmin (optional)

sudo apt install phpmyadmin # interactive

PHPmyAdmin no longer let's you login with the root MySQL user. So you'll have to create a database and a user to use with Opencart from the command line. Once it's created you can use that to login to PHPmyAdmin.

Replace DBNAME, USERNAME, PASSWORD in the commands below

mysql --user=root
mysql> CREATE DATABASE DBNAME ;
mysql> CREATE USER 'USERNAME'@'localhost' IDENTIFIED BY 'PASSWORD' ;
mysql> GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'localhost' ; -- grant access to ALL MySQL databases
mysql> GRANT ALL PRIVILEGES ON DBNAME.* TO 'USERNAME'@'localhost' ; -- grant access to Opencart database

Setup virtualhost file and domain

create virtualhost

curl -s https://raw.githubusercontent.com/aamnah/bash-scripts/master/setup/virtualhost.sh | bash -s mydomain.com

# add `root` to `www-data`
adduser root www-data

# Change group ownership for `/var/www` to `www-data`
sudo chgrp -R www-data /var/www/*

# Give write permission to the group
sudo chmod -R g+w /var/www/*

# chmod g+s forces new files and dirs to pick up the group owner (www-data),
# making sure that permissions change propagates
# (`-s` means set user or group ID on execution)
find /var/www -type d -print0 | sudo xargs -0 chmod g+s

Install OpenCart

# move to project directory
cd /var/www/domain.com/public_html

# delete default index.html created by virtualhost script
rm index.html

# download OpenCart release
# https://github.com/opencart/opencart/releases
wget https://github.com/opencart/opencart/releases/download/3.0.3.2/opencart-3.0.3.2.zip

# unzip the files
unzip opencart-3.0.3.2.zip

# move stuff from the `upload/` folder to project root
mv upload/* .
mv upload/.htaccess.txt

# Rename config files
cp config-dist.php config.php
cp admin/config-dist.php admin/config.php

# Make sure the file permissions are right
chmod 755 config.php admin/config.php
chown -R www-data:www-data /var/www/

# Rename .htaccess file
mv .htaccess.txt .htaccess

# Enable Rewrite module (needed for clean URLs, will give errors otherwise)
a2enmod rewrite

# Restart Apache
service apache2 restart

Now go to your domain or IP in the browser and complete the installation. Afterwards, cleanup

# delete install/ and empty upload/ dir
rm -rf install/ upload/
