ClosedHow install php 8.1?

Hi

My server runs the latest php version 8.0.12 (ubuntu 20.04)

How can I update to php 8.1 ?

Current Version 2.1

good question

I don’t think most WordPress plugins are tested/support 8.1. I would wait full 8.1 support rather than try get sites work 1ms faster and risk having bugs with unsupported plugins.

If you really want to try maybe try that tutorial just make backup first if something goes wrong. How to Install or Upgrade PHP 8.1 on Ubuntu 20.04 - Cloudbooklet

8.1 is not compatible with most WordPress stuff.
So wait on 8.0
