Prerequisite Software for Nextcloud

This document assumes the following software and services have been already installed and configured:

• Web Server

• Database Server

• Redis

PHP 8.2

Nextcloud version 25.0.4 as released in February 2023 recommends PHP version 8.2. Official Ubuntu 22.04 packages provide PHP version 8.2.

Note

Its prefectly safe to install and run different PHP versions on the same system.

To install PHP version 8.2, the PHP PPA of Ondřej Surý is a recommended addition to your systems repositories:

$ sudo add-apt-repository ppa:ondrej/php

After that you need to explicitly choose the 8.2 version of any PHP related package you want to install.

Nextcloud also requires and recommends the following PHP modules installed, if using Nginx as web server and MariaDB as database server:

    php8.2-bz2 \
    php8.2-curl \

The installation process will start the PHP 8.2 service automatically. Since it needs configuration we stop it for the time being:

$ sudo systemctl stop php8.2-fpm
