I need to support a website written for PHP 5.3.22 for one of the clients I'm migrating to this new ISPConfig server. I'm following this tutoriallHow To Use Multiple PHP Versions (PHP-FPM & FastCGI) With ISPConfig 3 (Ubuntu 12.10) and I've got stuck at the step: The response was "No sources found for PHP5" I had already uncommented the ppa's in the sources.list for sources, but still not found. So I proceeded to add this PPA ppandrej/php and uncommented the source there also. Still same problem. Any ideas please?
