Dear Julien,
I was wondering why a bunch of OCaml-related packages were not
migrating, and realized one reason was elpi being out-of-date on many
architectures... which led me to the following changelog item:
elpi (1.16.7-2) unstable; urgency=medium
.
* Limit the architectures where the package builds,
until upstream re-enables them.
When the list of supported architectures for a package changes, it is
not enough to change the source package; you also have to ask for
removal of the binary packages on new-ly unsupported architectures from
the archive (RM bug on ftp.debian.org).
Cheers,
