   /usr/share/man/sr/man1/xzmore.1.gz]: [The newly introduce files that are not included in the package]


Answer: Issue: The upstream version was released with a new man page translations (Italian and Serbian). These new files were installed during the build, but were not included in the final rpm.
Resolution: Include the new localization files in the package, e.g. adding the following to the %files section of the main subpackage

%lang(it) %{_mandir}/it/man1/*xz*
%lang(sr) %{_mandir}/sr/man1/*xz*
