[Pkg-samba-maint] Bug#961867: python3?-talloc multiarch support is broken because of the dependency on python

[Francois Gouget]

Package: python-talloc
Version: 2.1.14-2
Severity: normal

Dear Maintainer,

python-talloc is 'multiarch: same' but the i386 package is not coinstallable
with the amd64 one because of their python dependency.

The issue is that python-talloc:i386 depends on python:i386, while
python-talloc:amd64 depends on python:amd64. But python is multiarch
allowed and this causes a conflict when trying to install both i386 and
amd64.

python3-talloc 2.3.0-5 has the same issue in Debian Testing but with
python3 instead of python.

Maybe what was intended is to have a python3:any dependency instead of a
regular python3 one? So this would make it:

Depends: libtalloc2 (= 2.3.0-5), python3:any (<< 3.9), python3:any (>= 3.8~), libc6 (>= 2.4), libpython3.8 (>= 3.8.2)

Unfortunately I don't know enough about python3-talloc to know if that would make sense. This multiarch howto section seems particularly relevant:
https://wiki.debian.org/Multiarch/HOWTO#When_to_use_:native_and_when_to_use_:any.3F

The impact is that this prevents Wine from using the libnetapi
library for 32-bit Windows applications because libnetapi is part of
samba-libs, which depends on python3-talloc.
