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
