Bug: Your Composer dependencies require a PHP version ">= 7.4.0

Situation

I try to install grocy on virtual machine with virtualbox. The virtual machine runs this software:

• Debian Buster 10.7 (Package source: http://ftp.de.debian.org/debian/)
• nginx 1.14.2
• PHP 7.3.19
• sqlite3 3.27.2
• grocy 3.0.1

I configure like it is described in the README.md. Only differences I have to make are the following:

1. I change in the default language to german in the data/config.php.
2. I change in the default currency to EUR in the data/config.php.
3. Instead of try_files $uri /index.php$is_args$query_string; (copy of the README.md) I writetry_files $uri /app.php$is_args$query_string; in nginx configuration
4. Instead of index index.php (a typical default for php applications) I write index app.php in nginx configuration.

The reason for changes 3 and 4 are the fact that there isn’t any index.php in the the latest release of grocy. (Is that maybe also a little bug in the README.md?)

Error

When I browse to this local grocy server, I get the following error.

• In the title of the browser tab 403 Forbidden
• In the content area: Composer detected issues in your platform: Your Composer dependencies require a PHP version ">= 7.4.0".

Why PHP 7.3 isn’t enough? (It is stil a supported version.) The README.md says something different then the error.

Based on user reports, the minmimum required/working runtime is PHP 7.2 with SQLite 3.9.0 However, I don’t really care about supporting old runtime stuff, currently everything is only tested against (means 100 % works with) PHP 7.4 with SQLite 3.27.2

I run Debian stable and use deb.sury.org for PHP packages (and https://nginx.org/packages/mainline/debian/ for nginx, since I just don’t want to wait years to be able to use new features…).

Thanks @berrnd! Regarding Debian, are you installing newer versions of PHP via PPA? Or are you running a testing version of Debian? The latest PHP I can see in the repos for Debian Buster (10) is PHP 7.3.
