this is what i use, unless you meant letting the script instal the stuff
i ran the script a couple times on 3 different machines 1 of them was a vm (all of them were fresh installs)
it always results in this exact error
seems like you also had MariaDB setup before running this script.
"msg": "unable to connect to database, check login_user and login_password are correct or /home/sturdygamer/.my.cnf has the credentials. Exception message: (1045, \"Access denied for user 'root'@'localhost' (using password: YES)\")"
The above line has come up multiple times in your log. the install.py script works fine on fresh servers without anything installed prior.
