Trying to remove index.php from urls - .htaccess

Question

**I'm working on an apache secured web server hosted on an ubuntu-server.16.04
I'm sending on prod my first project on symfony and I did quite well since now. I'm trying to rewrite url so when I want to go on my project dashboard, the url would be "../dashboard/" instead of (actually like this) "../index.php/dashboard/"
But when I try to go on this url, the server redirect me out of the symfony app and throw me a basic apache 404 error, not a symfony handled error.
I think this can be edited in the .htaccess file but I can't find out how to make him perform all url as symfony routes, that's my question.
Tried multiple code found on google
htaccess
DirectoryIndex index.php
<IfModule mod_negotiation.c>
Options -MultiViews
</IfModule>
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
RewriteRule ^(.*) - [E=BASE:%1]
RewriteCond %{HTTP:Authorization} .
RewriteRule ^ - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^index\.php(?:/(.*)|$) %{ENV:BASE}/$1 [R=301,L]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^ - [L]
RewriteRule ^ %{ENV:BASE}/index.php [L]
</IfModule>
<IfModule !mod_rewrite.c>
<IfModule mod_alias.c>
RedirectMatch 302 ^/$ /index.php/
</IfModule>
</IfModule>

You need to enable apache rewrite.
Please follow these steps :
In a terminal use the following commands:
$sudo a2enmod rewrite
Change AllowOverride in apache conf file:
$sudo nano /etc/apache2/apache2.conf
Change the AllowOverride from None to All in this block
<Directory /var/www/>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>
At last, restart apache2
$sudo service apache2 restart
