Error when adding admin user during web install

I get the following error when attempting to add a user in step 3 of the web installer:

I followed instructions exactly, have completely wiped my VM and started from fresh and am still getting this error.

validate.php outputs this:

Component Version
LibreNMS 1.48
DB Schema Not Connected (0)
PHP 7.2.10-0ubuntu0.18.04.1
RRDTool 1.7.0

[FAIL] config.php does not exist, please copy config.php.default to config.php

I am unsure what else I can do to correct the Mysql DB issues listed in the validate.php.
Any help is greatly appreciated.

Can you pastebin the logs/librenms.log file?

Some how you made it to the add user stage without your database schema being built.

copy config.php.default to config.php, update it with DB credentials, run lnms migrate and ./adduser.php if you want to do the steps manually.
