Enabling Error reporting in magento2 is little tricky , as magento2 now comes with 3 different modes

• Default
• Developer
• Production

Magento2 by default install in “default” mode and thats why you dont get the error log at the front-end of the site , that can a viewed at magento error log . You may check the complete details over here http://devdocs.magento.com/guides/v2.0/config-guide/bootstrap/magento-modes.html

How to enable developer mode in Magento2

This is must have if you are a developer and building extension and template for magento2 , magento provide a command for this purpose . Login in to your linux terminal and under magento execute

php bin/magento deploy:mode:set developer

and it will enable the developer mode under your magento instance for production mode you can set the mode to production or default .

still if you are experiencing in error reporting you can give a try by renaming local.xml.sample to local.xml under pub/errors

if you are changing mode then magento2 changes the ownership and file permission  so you will require to set the permission and ownership again

the same command which you execute during magento2 installation
