Need Help: install script

Topic
Installation

What have you already tried?
bash <(wget -qO- https://kubrick.roen.us/pipass/scripts/install.sh)

Additional context
I am running latest raspbian on an RPi 4. I have pihole already set up.

Relevant logs or images
When running the install script it asks for the web document root. I entered "/var/www/html".
The script then continues and fails as follows:

Building /etc/sudoers line to add...
Checking if /etc/sudoers is already set up...
/etc/sudoers is already set up. No need to add another line.
Setting up Git repository and collecting PiPass files.
fatal: remote origin already exists.
fatal: not a git repository (or any of the parent directories): .git

If you’re running Debian 10 Buster, run sudo apt install php7.3-curl and retry the install script.
