Error 500 Internal Server

So I've tried all 3 ways to install, I verified php and apache2 modules were all loaded and up-to-date, tried all possible solutions in the official Troubleshooting help, I've fixed the permissions, I've reinstalled it 10 times already, and I'm running on Ubuntu 16.04 LTS, Apache

https://frozola.org

Is where I'm trying to install it from.

Not sure what your asking. I don't see any 500 errors, and wouldn't be able to tell what's going on fro the web side anyway. 500 error, means a configuration problem, so you need to look at the apache error log to see what's causing it.
