Thanks Fokko again for the check on licences :).

I took a closer look and:

   - The RAT tool is supposed to be run on the source package not the
   binary releases. While the binary releases also follow the same guidelines
   for containing license headers (
   https://www.apache.org/legal/src-headers.html#faq-exceptions). RAT might
   give some misleading results. The binary releases contain some artifacts
   that are generated from sources (egg-info) and the *setup.cfg* generated
   by setuptools fall into this category (our original setup.cfg) contains
   Licence header, it's just stripped out by setuptools. Even the RAT tool
   mentions that: "*Generated files do not require license headers*". It's
   the same for airflow 1.10 releases. So I think this is perfectly fine.
   - Regarding the licenses. I think it's a bit more complicated. I took a
   look and it seems that "licences" folder is excluded in our .rat-excluded.
   The comment (in our .rat-excludes) is:

# Apache Rat does not detect BSD-2 clause properly
# it is compatible according to
http://www.apache.org/legal/resolved.html#category-a
...
licenses/*


   - LICENSE-flask-kerberos.txt- is BSD-2 clause license
   <https://opensource.org/licenses/BSD-2-Clause> - this is perfectly ok
   according to http://www.apache.org/legal/resolved.html#category-a
   - LICENSE-d3js.txt - is BSD-3 clause license
   <https://opensource.org/licenses/BSD-3-Clause> that is also perfectly
   ok  according to http://www.apache.org/legal/resolved.html#category-a

I think however that our exclusion in .rat-excludes is too broad -it should
only exclude specifically the licenses that we know are not detected by RAT.

Regarding the SHA512 - I just used the same script that we are using for
signing and producing SHA for airflow released (dev/sign.sh) and what it
does is:

* gpg --print-md* *SHA512*
*apache-airflow-backport-providers-celery-2020.5.20rc2-bin.tar.gz*
apache-airflow-backport-providers-celery-2020.5.20rc2-bin.tar.gz:
22E8D410 72BF03E2 7CE31489 8FF1FBD1 AE1D9AF9 1EEBC051 6EADC693 D216B58B
305EDB2B
 27939B5A C983DF55 DDA33D50 FD4EFD85 3EA73AC6 4BDD9E42 EEC9A207

But when I run it with shasum I got it perfectly ok as well - a bit
different format  but seems the signature is the same:

*shasum -a 512
apache-airflow-backport-providers-celery-2020.5.20rc2-bin.tar.gz
    *
22e8d41072bf03e27ce314898ff1fbd1ae1d9af91eebc0516eadc693d216b58b305edb2b27939b5ac983df55dda33d50fd4efd853ea73ac64bdd9e42eec9a207
 apache-airflow-backport-providers-celery-2020.5.20rc2-bin.tar.gz

Can you please re-download it and double check if you still have problem
with the signature ? Maybe you modified it by accident after downloading
while extracting the content?

J.
