The code written in https://github.com/TandoorRecipes/recipes/blob/develop/cookbook/connectors/connector_manager.py makes use of features introduced in Python 3.10, such as the structural pattern matching (match and case) and the union types with the pipe operator (|) which are not compatible with Python 3.9. That's why the minimum required python version for the manual installation should be python version 3.10.
Updated the manual installation file to get everybody up and running.
There were missing requirements like the nginx installation and so on.
Now a first time linux user should be able to get this up and running.
In order to run over HTTPS* django requires the X-Forwarded-Proto header sent from the nginx proxy. I didn't add everything needed for TLS, but this header works with HTTP and HTTPS so I figure it might save a few people some time if they ever decide to secure their installation.
\* specifically, I noticed that image URLs are requested over HTTP instead of HTTPS even when the main page is HTTPS until this header is sent
I just went through a manual install on DietPi / Debian Unstable, and found that the manual needed some improving, this method works, whereas following the original manual was not a success for me.
The only line I would say I am unsure about is this one:
"Give the user permissions: `chown -R recipes:www-data /var/www/recipes`"
As I am not sure whether these permissions are necessary for this to work.
Hope this is useful, let me know if I can make further improvements.
