CI in a Linux environment setup

I have tried your solution with no success. this is de code of my currently .htaccess

Code:

#RewriteEngine On
#RewriteCond $1 !^(index.php|styles|scripts|images|jQueryUI|fonts|uploads|media|robots.txt)
#RewriteRule ^(.*)$ /20190916Bibliotecas/index.php/$1 [L]1
# Checks to see if the user is attempting to access a valid file,
# such as an image or css document, if this isn't true it sends the
# request to the front controller, index.php
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

I have tried the solution with and without the first line and nothing

Code:

RewriteEngine On

I don't see the welcome message because this is copy of folder straight from CI version 3.x.x I was going to try a migration  to 4.x but it seems it won't be that simply of copying and paste my controllers, views, jQuery,etc.

I'm gonna try to install xampp on a new virtual machine with Linux maybe Ubuntu just to check if its thing of my distro or CI, and try to load my project https://we.tl/t-me9F2Obn7g  from there.

Could it be that CI is not recognizing properly my URLs?, permissions on htdocs are set to owner myself.
