edgarrmondragon opened a new issue #18075:
URL: https://github.com/apache/airflow/issues/18075
### Apache Airflow version
2.1.2
### Operating System
Ubuntu 20.04
### Versions of Apache Airflow Providers
NA
### Deployment
Other Docker-based deployment
### Deployment details
Ubuntu Docker image, Airflow installed inside a `virtualenv` in the image.
### What happened
Trying to pip-install Airflow in a virtualenv where `setuptools` is
`>=58.0.2` fails:
```
Orchestrator 'airflow' could not be installed: failed to install plugin
'airflow'.

Complete output (1 lines):
error in Flask-OpenID setup command: use_2to3 is invalid.
```
The `setuptools` team deprecated `use_2to3` (see
https://github.com/pypa/setuptools/issues/2086) recently and this is breaking
installation of packages which rely on that legacy key. In the case of Airflow,
`Flask-OpenID`, required by `Flask-AppBuilder`, is the offending dependency.
See https://github.com/mitsuhiko/flask-openid/blob/v1.2.5/setup.py#L32.
This should probably be fixed by that project's maintainers, but we
(Meltano) thought it was a good idea to file this issue here in case Airflow
users run into the problem. Just removing `use_2to3` seems to work 😃.
### What you expected to happen
Airflow's dependencies should be prepared for new versions of `setuptools`
and Python (`3.10`).
### How to reproduce
```console
$ python -m venv venv
$ source venv/bin/activate
(venv) $ pip install "setuptools==58.0.2"
(venv) $ pip install apache-airflow
...

### Anything else
The current workaround it to make sure a version of `setuptools` prior to
`58.0.0` is installed in the active Python environment.
