Hi Bastien,
The affected packages have unsatisfiable cross Build-Depends, because
their transitive dependency on libmagickcore-dev, libmagickwand-dev or
libmagick++-dev is unsatisfiable. In general, Architecture: all packages
can never satisfy cross Build-Depends unless marked Multi-Arch: foreign.
In this case, such a marking would be fatal as we have seen in #856601.
The other major route, converting them to arch:any, is blocked by
#813455. That's bad.
So I think I came up with a workaround that works today. debian/control
says that these packages are transitional and you said on irc that they
will be provided by their dependency. So why not provide them today?
Those transitional packages are completely empty. By providing them (in
addition to producing them), upgrade continue to work, but since the
providing package is arch:any, we can satisfy cross Build-Depends. After
buster, you leave the Provides and just remove the transitional
packages.
The attached patch implements just that. What do you think?
Helmut
