   The problem is likely with the `python-daemon` version you have installed. The 'python-daemon` 2.2.4 solves this problem (it is Python 3.8 only) and it was released a year ago
   
   Probably you have not installed airflow in recommended way and you have some really old version of this dependency (and probably others as well). 
   
   The recommended installation method is here: https://airflow.apache.org/docs/apache-airflow/stable/installation.html#installation
   
   Can you please confirm that? I will add extra limitation to Airflow to require 2.2.4 or above for python 3.8, but in the meantime you can just upgrade python daemon and it should work (but it's best to install airflow according to our recommendations to avoid similar problems).
   
   More info:
   
   According to latest constraints we are using latest `python-daemon` released: 2.2.4: https://github.com/apache/airflow/blob/constraints-2-0/constraints-3.8.txt#L322
   
   The error you are experiencing was fixed in 2.2.4 version:

   ```
   * Create the socket and catch “non-socket” errors.
    
     Closes: Pagure #34. Thanks to Miro Hrončok for the bug report and
     patch.

   The issue (python 3.8) is described here: https://pagure.io/python-daemon/issue/34
   
   And the fix is here: https://pagure.io/python-daemon/c/b708912
