Hi,

I'm trying apply patch to an upstream debian package

recipe looks like:

inherit dpkg

SRC_URI = "apt://${PN} \
file://files/mypatch.patch \
"


during  do_dpkg_build, I've got the error:

 dpkg-source -I --before-build nano-2.9.3
dpkg-buildpackage: info: host architecture amd64
 fakeroot debian/rules clean
dh clean --parallel

How fix it ? 
Can you confirm that patching an upstream package is supported ?
