retitle 1106308 widelands: FTBFS: Error: Licence file changed. thanks
Hello. When fixing this, please stop relying on the the exact copy of the GPL-2 which base-files provides, as it can change from time to time for minor editorial changes (as it was the case here). Or maybe use whatever is in /usr/share/common-licenses unconditionally and without giving an error. An idea would be to check that the files match but only when creating a new source package. Unfortunately, I don't know if such thing is possible. Another idea that would probably work is to show a warning message (but not an error) for 10 minutes if the files do not match. That would still make the package buildable indefinitely, but would be annoying enough for anybody creating a new source package. Yet another idea would be to use debian/source/local-options (in the git repo, but not in the source package), but I have never tested that. Thanks.
