Re: Bug#996627: kodi-data: Kodi cannot be installed on a foreign architecture

Hi,

I think this bug has been diverted to being able to use widevinecdm.
While that turns the original request a little academic, there still is
a bug there.

This raises the question of why kodi-data depends on
python3-pycryptodome. There are basically two reasonable answers:

a) It provides programs (something you can run from a shell) that happen
   to use python3-pycryptodome. In this case, kodi-data also must depend
   on a python3 interpreter.

b) It provides python modules that use python3-pycryptodome (to be
   imported by other packages). In this case, kodi-data must not be
   marked Multi-Arch: foreign.

So regardless of the widevinecdm issue, this is a bug in kodi-data.

I vaguely guess that we're in case b) here. If you don't like removing
Multi-Arch: foreign from kodi-data, there is another way out: Move the
python modules to a new kodi-python-addons package. Move the relevant
python dependencies to this package. Make it Architecture: any (not
all). It can become Multi-Arch: same, but that won't help much. Any user
of it must depend on kodi-python-addons directly. A dependency from
kodi-data to kodi-python-addons is not sufficient (as kodi-data is
supposed to remain Multi-Arch: foreign).

Now this all doesn't solve the problem of foreign installation, but we
can only really think about that once we have correct metadata.

Once it has been fixed and a week has passed, we should look into
https://bootstrap.debian.net/foreign_install/kodi.html. It gives a good
overview of the outstanding metadata issues.

I hope this makes sense to you. If it does not, please don't hesitate to
ask.
