magento local setup localhost ends up 404

[tolsonhann]

I have followed the set up instructions for my ubuntu local environemnt using:

virtualbox nginx composer mariaDB

after installing everything logging into git, magento cloud, and creating a DB called magento the 

php bin/magento setup:install \

   --admin-firstname=name \

   --admin-lastname=last name \

   --admin-email=my email \

   --admin-user=my name \

   --admin-password=password1 \

   --base-url=http://hi.local/ \

   --db-host=localhost \

   --db-name=magento \

   --db-user=name \

   --db-password=password \

   --currency=USD \

   --timezone=America/Chicago \

   --language=en_US \

   --use-rewrites=1

goes well and seems everything is working.

I restart nginx and my localhost is:

404 Not Found

---

nginx/1.14.0 (Ubuntu)

.

Any ideas what's configured improperly? or maybe I am missing something obvious..

Also, I am unable to delete files because I don't have the correct permissions granted. How can I change that?

Using sudo rm command granted me privileges.
