I'm trying to install Virtumart on my apache server.

I used this reference as my installation guide: https://hostadvice.com/how-to/how-to-install-joomla-on-an-ubuntu-18-04-vps-or-dedicated-server/

This is where got the package: http://virtuemart.net/downloads (full install)

The install page came but it's not working because the next button and some components are missing.

I need some expert help to fix this. I tried different browsers, but still got the same result.
