Configuring Magento 2 on Ubuntu

I successfully installed Magento 2 and now trying to get working.

If I run apache2 –version

Apache2 appears to be running.

MySql version and I was going to check PHP version but there are multiple options so not sure what to do there.

When I try to open ‘localhost’ in the browser it redirects to localhost/Setup but cant load.

I dont actually think Magento is installing correctly. I’m running it as sudo.
