[Debian-astro-maintainers] Bug#983306: astrometry.net combines incompatible GPL licenses

[Rik Mills]

Package: astrometry.net
Version: 0.82+dfsg-1

As a result of the rejection of the stellarsolver source package by FTP
masters for combining incompatible GPL licenses.

https://lists.debian.org/debian-qt-kde/2021/02/msg00114.html

it was pointed out that the library tree in question (libkd) is copied
from the astrometry.net project sources, and that a similar issue exists
in it.

See: https://github.com/dstndstn/astrometry.net/issues/212

astrometry.net have resolved the issue by swapping the GPL2 only
licensed code (which was copied by astrometry.net from the linux kernel)
with the FreeBSD implementation.

however, if the license issue is/was valid, then as commented in the
upstream issue by DD Pino Toscano, it may render current and some
previous Debian binaries undistributable.
