Introduction

This document will guide you to upgrade PHP-8.1 for Faveo Helpdesk.

Before proceeding further check your current PHP version. To find out which version of PHP you are currently using, run this in the Terminal or Windows command prompt.

If you are running PHP 7.x, you can continue with this guide to upgrade to PHP 8.1

For Ubuntu and Debian

Type the following command to remove the existing PHP version.

sudo apt-get purge php7.*

Press y and ENTER when prompted.

After uninstalling packages, it’s advised to run these two commands.

sudo apt-get autoclean

sudo apt-get autoremove

Add Ondřej Surý’s PPA repository
