Debian 11 install

[ccwrapper]

Hi everyone, I'm doing this:

Clean install of Debian 11.7 (netinstall), then
apt install sudo curl gpg, then
adduser myuser sudo, then these steps:

wget -qO- https://dl.packager.io/srv/inventree/InvenTree/key | sudo apt-key add -
sudo wget -O /etc/apt/sources.list.d/inventree.list \
https://dl.packager.io/srv/inventree/InvenTree/master/installer/debian/11.repo
sudo apt-get update

So far so good. Then the main part:
sudo apt-get install inventree

And here I get this:

# Set permissions for data dir and media: /opt/inventree/data
chown: cannot access '/opt/inventree/data': No such file or directory
# Setting up InvenTree config values
# Writing the settings to the config file /etc/inventree/config.yaml

chown: cannot access '/etc/inventree/config.yaml': No such file or directory

The installer for some reason doesn't create directories in /opt and /etc, and doesn't create config.yaml file.

Nevertheless, the installer configures nginx and generates "admin user data", but opening web page ends with "502 Bad Gateway" (maybe because of some other things though).

@ccwrapper do you run into similar issues if you run the quick installer:

wget -qO install.sh https://get.inventree.org && bash install.sh

This time it worked! Thanks!

Though I've tried this install script beforehand and it threw some errors that's why I switched to step by step installation.
