Appstream hints no longer available

[Raphael Hertzog <hertzog@debian.org>]

Hello Matthias,

I recently opened my owner@tracker.debian.org mailbox and I found
hundreds of errors:

----
Task UpdateAppStreamStatsTask failed with the following traceback.

HTTPError
404 Client Error: Not Found for url:
https://appstream.debian.org/hints/sid/non-free-firmware/Hints-amd64.json.gz
----

It looks like that the files required for the tracker.debian.org
integration have disappeared since mid-December. Can you add them back?
Shall I disable/remove the integration for now?

Thank you in advance!
