When I'm trying to install "Joomla_3.8.6-Stable-Full_Package", with the URL "http://localhost/mysite", the system redirect me to "http://localhost/mysite/installation/index.php", and the page just display the text "Error".

Any one with the same problem or some one that can help me please?

Could you check if you have the following libraries available in Apache?
mod_mysql, mod_xml, and mod_zlib

You'll need those, see: https://docs.joomla.org/Technical_requirements

Hi, I had changed my PHP configuration like this: "display_errors On", and this is my error detail:

Error: Call to undefined function Joomla\CMS\Language\simplexml_load_file(): Call to undefined function simplexml_load_file()

I'm going to check your recommendation.

Thanks.

I solved it:

Open a terminal and execute:

sudo apt-get install php7.2-mysqli
sudo apt-get install php-pear
sudo apt-get install php7.2-mysql
sudo apt-get install php7.2-curl
sudo apt-get install php7.2-json
sudo apt-get install php7.2-cgi
sudo apt-get install php7.2
sudo apt-get install libapache2-mod-php7.2
sudo apt-get install php7.0-mcrypt
sudo /etc/init.d/apache2 restart

Open your browser: and enter your URL. For example in my case: "http://localhost/mysite/", Joomla will redirect you to "http://localhost/mysite/installation/index.php". Follow the installation steps

Good to hear that you've solved it.

If you run into any other problems, I have installed somewhat more PHP libraries on my VPS:
mbstring, opcache, soap, xml, (and for Nginx server fpm)
