   I am also wondering why I get this error when testing the backported version.
   
   ```
   _______________________________________________________ ERROR collecting tests/providers/amazon/aws/operators/test_imap_attachment_to_s3_system.py _______________________________________________________
   ImportError while importing test module '/opt/airflow/tests/providers/amazon/aws/operators/test_imap_attachment_to_s3_system.py'.
   Hint: make sure your test modules/packages have valid Python names.
   Traceback:
   /usr/local/lib/python3.6/site-packages/_pytest/python.py:513: in _importtestmodule
       mod = self.fspath.pyimport(ensuresyspath=importmode)
   /usr/local/lib/python3.6/site-packages/py/_path/local.py:701: in pyimport
       __import__(modname)

       from airflow.providers.amazon.aws.example_dags.example_imap_attachment_to_s3 import S3_DESTINATION_KEY
   E   ModuleNotFoundError: No module named 'airflow.providers'
   ```
   
   2.0.0 works fine.
   
   I ran the prepare backport script `./scripts/ci/ci_prepare_packages.sh amazon postgres mysql`.
   
   @turbaszek do you have an idea?
   
   EDIT:
   
   @potiuk do you have any idea? I recreated the whole breeze env i.e. cleaned docker (`docker system prune --all`)
