-OS : DEBIAN 10 on VBOX
-ruby version ruby 2.5.5p157 (2019-03-15 revision 67260) [x86_64-linux-gnu]
-rails version Rails 5.2.3
-you will find in download the steps i did initially and the solution of tons of problemes(don't worry about the version as i tried mulitple ones but sticked with 4.0.4)

Also :
- bundle exec ruby /usr/bin/rails server b 0.0.0.0 webrick -e production -p 3001
works perfectly(had to change port cuz already in use)
but in apache2 initially had an error page showing there is a probleme with passener
then i did
sudo passenger-install-apache2-module

and made sure to follow the steps and correct the problemes as suggested
and passenger-config validate-install
everything is ok :) for apache2 and passenger
