[Solved ] :Upgrade help - PHP ?

[chewiesw]

I am trying to upgrade from 1.4 (working) to 1.6.2. I am aware that I need to upgrade my PHP version before I upgrade roundcube.

Raspberry OS – Buster
NGINX


chew@mail:~ $ php -v
PHP 7.3.31-1~deb10u4 (cli) (built: Jun 19 2023 19:10:11) ( NTS )
Copyright (c) 1997-2018 The PHP Group

Roundcube/installer
Checking PHP version
Version:  OK(PHP 7.0.33-0+deb9u12 detected)

NGINX
location ~ \.php$ {
   try_files $uri =404;
    fastcgi_pass unix:/run/php/php7.0-fpm.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;

I have downloaded php7.3-fpm and it is running. When I change the nginx fastcgi to :    fastcgi_pass unix:/run/php/php7.3-fpm.sock;

I get a HTTP 500 error when I open the roundcube URL.

What have I missed or what am doing wrong?

   location ~ \.php(?:$|/) {

        fastcgi_split_path_info ^(.+\.php)(/.+)$;

check
/etc/php/7.4/fpm/pool.d/www.conf

user = www-data
group = www-data
listen = /run/php/php7.4-fpm.sock

Solved. I re-installed php 7.3 fpm and all of it modules, changed my nginx config and it worked. No HTTTP 500 error.

I must have missed a module the first time.
