The popular Ondřej Surý’s PPA has built the package for all current Ubuntu LTS: Ubuntu 18.04, Ubuntu 20.04 and Ubuntu 22.04.

1. First, open terminal or connect to your Ubuntu server and run command to add the PPA:

LC_ALL=C.UTF-8 sudo add-apt-repository ppa:ondrej/php

Run sudo apt install software-properties-common in case the command does not exist. And, type user password (no asterisk feedback) when it asks and hit Enter to continue.

2. Then, install Php packages accordingly. For example, install apache2 module and mysql module via command:

sudo apt install php8.2 libapache2-mod-php8.2 php8.2-mysql

Or install the FPM-CGI binary for use with Nginx:

sudo apt install php8.2 php8.2-fpm php8.2-mysql

For Ubuntu 18.04, run sudo apt update first to refresh package cache.

After installed it, remember to configure your http server (apache 2 or nginx) for the new PHP package, and configure php8.2 via files under ‘/etc/php/8.2/’.

To remove the package, simply run command:

sudo apt remove --autoremove php8.2 libapache2-mod-php8.2 php8.2-*
