Can someone help me please. I am trying to install the software but it is giving me this error

Required PHP version less than 8.1.0 AND found version is : 8.1.29

Why does this require an OLDer version of PHP and is there a work around for this as my server does not support OLDER php for some reason
thank you all in advance.

In installation was bug that required different version that Osclass itself.
Go to required PHP version, after installation you can switch.

The server software does not allow anything less than 8.1 sadly.

Their support has informed me :

PHP 8.0 is unavailable on Ubuntu 22.

Any other ways to get this to install or plans to fix the bug?

Issue will be fixed in next Osclass release.

You may fix it in file:
\oc-includes\osclass\install-functions.php

  $php_min = (defined('PHP_MIN') ? PHP_MIN : '7.2');
  $php_max = (defined('PHP_MAX') ? PHP_MAX : '8.1');
