If you download a new upstream source file, move it to the parent of the current source directory. Make sure it has a name with a Debian compliant version number, say foo-2.1.tar.gz. cd into the current source directory. You can port the current patches to the new sources with uupdate ../foo-2.1.tar.gz Now cd into the new source directory and look for any failed patches find . -name *.rej Once you have cleared these up, build and check the package as described above.
