Upstream GPL-3+ vs debian/* GPL-2+

[Eriberto Mota <eriberto@debian.org>]

Hi,

I have a doubt about a situation.

The upstream source code is GPL3+. Packaging is a derivative work and
I think that it must be GPL. So, GPL-3+, right? Or can the debian/* be
GPL-2+?

Is GPLv3 compatible with GPLv2?

No. Some of the requirements in GPLv3, such as the requirement to
provide Installation Information, do not exist in GPLv2. As a result,
the licenses are not compatible: if you tried to combine code released
under both these licenses, you would violate section 6 of GPLv2.
-------------

Can someone confirm it?

Thanks.

Regards,

Eriberto
