Everybody on the Internet tells to build packages with debuild -uc -us, this answer for example, but I totally can't find what do these options mean, even the built-in help (debuild --help) doesn't tell anything about -uc and -us.
So what do these options mean?
Commands' built in 'help' is usually insufficient for this kind of thing.
If you had read the debuild manpage you'd find those are dpkg-buildpackage flags which are passed from debuild to dpkg-buildpackage and then would have been able to use dpkg-buildpackage's manpage to find the answer.
From the Xenial man page for dpkg-buildpackage:
-us Do not sign the source package.
-uc Do not sign the .changes file.
Edit (2025-06-15): In response to pokes in March, I wish to share that these options are still accurately stated in the manpage for
dpkg-buildpackageas I stated, even for the development release (Questing 25.10) so this hasn't changed since it was originally written.
