Breaks production Docker image: Celery 4.4.4 (known bug) lacks "future" module thus breaks airflow

[dinigo]

Hello. We are experiencing some issues in local development due to a celery using a module that it doesn't install anymore.

This happened when upping dependency version of celery 4.4.3 to 4.4.4

Apache Airflow version: 2.0 - Official docker image (apache/airflow:master)

What happened:

Commit aa89900 updated celery 4.4.3 to 4.4.4 with the bug reported in here celery/celery#6145. Celery 4.4.4 depends on future but doesn't require it.

All of our local environments are failing

What you expected to happen:
Restore celery=4.4.3 in the requirements files and rebuild the dockerhub images

How to reproduce it:
Start the image normally

Anything else we need to know:

Fixed in #9194 - the images should rebuild tonight (we have nightly builds) and they should contain celery 4.4.5

Thanks a lot @potiuk and @mik-laj! You saved my day :)
