Moodle 3.7 not loading properly after installation

I have a fresh Moodle 3.7 install in my Ubuntu 19.04 powered laptop, Apache2 as server, PostgreSQL for database and PHP 7.2. I've followed the steps in https://docs.moodle.org/37/en/Step-by-step_Installation_Guide_for_Ubuntu, except that I've used a PostgreSQL database (and it installed fine). But when I access `http://localhost/moodle/`, I see this screen: [![enter image description here][1]][1] It's like the CSS is not working. Chrome's console show a bunch of errors: [![enter image description here][2]][2] And I simply didn't find information on the web about these specific errors. My `/var/www/html/moodle` folder has all permissions (chmod 777 recursive). What am I doing wrong here? [1]: https://i.sstatic.net/sIltT.png [2]: https://i.sstatic.net/AMUA6.png
