@potiuk thanks. couldn't the airflow and python versions be inferred at runtime instead of pushing that complexity onto the user? in situations where a constraint file(s) is not defined, couldn't an error be raised?

We noticed that when if failed in our CI and this is fine when new version package breaks something.
- Temporary we upper bound limit it by https://github.com/apache/airflow/pull/36895
- The target solution could be tracked in: https://github.com/apache/airflow/issues/36897
For end users there the base recommendation is follow:
- [Installation of Airflow™](https://airflow.apache.org/docs/apache-airflow/stable/installation/index.html#using-pypi)
- [[Reminder] How to reproducibly install Airflow](https://lists.apache.org/thread/b8q1t3pvtky7y7mb2kjt4r2bz5bvz8qy)

the use of the installation on the official website using the constraints.txt + the command airflow standalone solve the problem

Ran into this on a fresh install today
I'm using 3.8 because that's what PyPI says: "Requires: Python <3.12, ~=3.8"
```
pip show apache-airflow
Name: apache-airflow
Version: 2.8.1
python --version
Python 3.8.18
lsb_release -a
Description: Ubuntu 22.04.3 LTS
Release: 22.04
Codename: jammy
```
## Steps to reproduce
Setup
```bash
conda create -n pipeline python=3.8.18
conda activate pipeline
pip install apache-airflow
airflow db init
```
Produces the following output
```

And the reason for both is explained in the link I posted. You can also watch my presentation from Airlfow Summit if you want to know all the technical details https://airflowsummit.org/sessions/2023/mastering-dependencies-the-airflow-way/
Those two sources go into deep dive why the answer for both your questions is no.
