Bug#517191: One example for #517191

["Nelson A. de Oliveira" <naoliv@debian.org>]

Hi!

Here is a warning that I am having on one package that I am using lintian:

W: libdownload1: copyright-refers-to-versionless-license-file usr/share/common-licenses/GPL
N: 
N:    The copyright file refers to the versionless symlink in
N:    /usr/share/common-licenses for the full text of the GPL, LGPL, or GFDL
N:    license, but the package does not appear to allow distribution under
N:    later versions of the license. This symlink will change with each
N:    release of a new version of the license and may therefore point to a
N:    different version than the package is released under. debian/copyright
N:    should instead refers to the specific version of the license that the
N:    package references.
N:    
N:    For example, if the package says something like "you can redistribute it
N:    and/or modify it under the terms of the GNU General Public License as
N:    published by the Free Software Foundation; version 2 dated June, 1991,"
N:    the debian/copyright file should refer to
N:    /usr/share/common-licenses/GPL-2, not /GPL.
N:    
N:    Severity: normal, Certainty: possible

The copyright part is:

======
The Debian packaging is (c) 2009, William Pitcock <nenolod@dereferenced.org>
and is licensed under the GPL, see `/usr/share/common-licenses/GPL'.
======

So if there is a "licensed under the GLP", without any versions, it should
consider that it's valid to use /usr/share/common-licenses/GPL, right?

Thank you!

Best regards,
Nelson
