Upgrade to PHP8.1

Hey @jasveer,

I can see you have an Ubuntu 16.04, that’s a really really really old one and it has been EOF a long time ago. You’ll need to upgrade it as soon as possible.

To do so, you can follow these steps:

remove unused packages and files

sudo apt autoremove -y **&&** sudo apt autoclean -y

Upgrade commands

sudo apt update -y **&&** sudo apt upgrade -y **&&** sudo apt dist-upgrade -y

Of course, before you run that, I’ll suggest creating a snapshot just to be safe in case something fails:

As for enabling PHP 8, usually the following works for updated systems :

sudo apt install lsb-release ca-certificates apt-transport-https software-properties-common -y

then enabling the repo

sudo add-apt-repository ppa:ondrej/php

and lastly, instaling php 8:

sudo apt install php8.1

Hello @jasveer

As with almost any upgrade between major releases of an operating system, this process carries an inherent risk of failure, data loss, or broken software configuration. Comprehensive backups and extensive testing are strongly advised.

To avoid these problems, we recommend migrating to a fresh Ubuntu 22.04 server rather than upgrading in-place. You may still need to review differences in software configuration when upgrading, but the core system will likely have greater stability. You can follow our series on how to migrate to a new Linux server to learn how to migrate between servers.
