Hi guys,
I have 4 versions of PHP installed and trying to update apps to the latest ones they support. What is the safe way to remove the old unused PHP versions?

Wish everybody a nice weekend!

Hello,

Maybe this topic in french could helps you :

Faire le ménage dans les versions php

Bonjour, J’ai plusieurs versions de php qui se cumulent au fil du temps. J’ai actuellement les versions 7.3, 7.4, 8.0, 8.1. Je doute que ces 4 versions soient nécessaire. Les commandes ci-dessous indiquent qu’il y a des paquets installés concernant ces 4 versions mais également que php7.3 n’a pas l’air de tourner sur le serveur. Donc inutile? php8.0-fpm.service tourne mais ne concerne aucune application si je comprends bien, donc pourrais-je supprimer php8.0 également? dpkg -l | grep php[0-9…

Hi,
You can read this too :

Php-fpm, 4 versions running, seriously?

Be carefull, Nextcloud use php8.1-fpm not php8.2-fpm. The command ls /etc/php/**/fpm/pool.d list also old versions of config file (example an old version of Nextcloud that was on an old yunohost with Debian 10 before migration to Debian 11 is not delete) This command is more useful to see which versions to keep : lsof | grep /var/run/php | awk '{print $9}' | sort -u | cut -d'/' -f5 | awk -F'-' '{print $1,$3}' | cut -d'.' -f1,2
