Getting Started with Guacamole Install

New to CasaOS and trying things out. Is there any config files that I need to change before I install Guac from the store? When I launch it after install it comes back with an error and not the setup screen. Or am I completely doing something wrong? Thanks.

Hello, I have a video here:

Thanks for the video.

I get as far as getting the initdb.sql file but when I try to go to /var/lib/mysql, it doesn’t exist. Not sure why the folder doesn’t exist. I have CasaOS running on Ubuntu 24.04
