I am new to drupal. I have downloaded and extracted drupal into a folder. I have installed apache and PHP on my Manjaro Linux.

here is my drupal specific apache conf:-

 Alias /noone/blogindrupal "/srv/http/noone/blogindrupal"
 <Directory "/srv/http/noone/blogindrupal">
    AllowOverride All
    Options FollowSymlinks Indexes
    Require all granted
 </Directory>

When enter http://localhost/noone/blogindrupal in the browser URL bar, I get drupal installation page which following notice red box:-

Also if continue and enter database information and press submit button, after few seconds I get Gateway Timeout error like:-

The gateway did not receive a timely response from the upstream server or application.

I suspect you are installing Drupal (or at least trying to) on a server running PHP 7.4, which is not currently compatible with the latest version of Drupal (8.8). There is an issue on drupal.org right here that details the current problems, including yours: https://www.drupal.org/project/drupal/issues/3086374 .

The highest supported version of Drupal 8.8 is currently 7.3: https://www.drupal.org/docs/8/system-requirements/php-requirements .
