All reports of duplicate-packaging-file for the archive. The extended description of this tag is:
Some packaging files obtain different names when they are copied from source to installation packages. Debhelper sometimes adds *.Debian extensions to NEWS, README and TODO files. That can be confusing.
Debhelper's behavior also depends on the filename.
This source package contains both a file with the proper name and also a file with incorrect name. Please remove the file as indicated.
Please merge all relevant information into the surviving file.
Refer to https://bugs.debian.org/429510 and https://bugs.debian.org/946126 for details.
This tag has not been emitted in any package tested by Lintian.
