RewriteEngine not allowed here magento and apache2 on VPS - .htaccess

Question

I've just installed Magento on my VPS (Debian 11), I must say Magento it's a pain compared to PretaShop and Wordpress, but I really need it.
After a painful installation, I run the page and I get the following:
Internal Server Error The server encountered an internal error or
misconfiguration and was unable to complete your request.
Please contact the server administrator at info#magento.mywebsite.ie to
inform them of the time this error occurred, and the actions you
performed just before this error.
More information about this error may be available in the server error
log.
Additionally, a 500 Internal Server Error error was encountered while
trying to use an ErrorDocument to handle the request.
Then I thought to check logs. So I opened the file magento.mywebsite.ie.error.log and there is a list of all the attempts, like the following:

The files .htaccess in my Magento new installation are exactly identical to the .htaccess that you would find here on GitHub:
Link: https://github.com/magento/magento2
You will find .htaccess in the parent folder magento2, another one in the Document Root "pub" inside magento2. My opinion is that the system is using the one in the parent directory, magento2, since if I delete that .htaccess, the webpage would show "This page isn’t working" instead of "Internal Server Error", so the error message would be different in this way.
And this is apache2.ssl.conf used as configuration file:

Please could you be so kind to help me with this? I have no experience at all about Apache issues, then I didn't know what else info I could provide to you. Hope you can help.

Answer 1

I solved the problem by adding the following line with the Parent Root Directory to my apache2.ssl.conf:
<Directory /home/elliot/web/magento.mywebsite.ie/public_html/magento2>
AllowOverride All
</Directory>
In this way also the parent directory has AllowOverride All.
