Question

No PHP 8.0 on Ubuntu 22.04? (8.1 and 7.4 still present)

I just upgraded to Ubuntu 22.04 from 20.04, via DO’s upgrade-in-place script. Everything seemed to work fine, but it appears to have also upgraded me from PHP8.0 to 8.1. Regrettably, not all of my PHP code runs on 8.1 yet, and I need to downgrade to 8.0.

I wouldn’t expect that to be an issue, but sudo apt list only reports entries for php8.1 and php7.4. Did I miss a memo that 8.0 isn’t available, or do I need to install a repo or PPA for some reason?

Or is my install borked somewhere? I have tried sudo apt update again, but that did not solve my problem.

Hi @davidmorgan,

You’ll need to install the specific packages for PHP 8.

First, you need the essentials:

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

You should already have the above, however, let’s not take any chances. Now, add the PHP repo:

  1. sudo add-apt-repository ppa:ondrej/php

Now you are ready to go. Type in

  1. sudo apt install php8.0

This should install PHP 8 for you. To install any PHP extensions you need to

  1. sudo apt install php8.0-<extension>

Hope that helps!
