Can't access backend nor frontend after upgrade... That's what i can see:
Magento supports PHP 5.6, 7.0.2, and 7.0.6 or later. Please read Magento System Requirements.
Got it already running with PHP 7.0.6
php bin/magento setup:upgrade
Which gives me:
[Magento\Framework\Exception\LocalizedException] Area code is already set
