Repost from buildservice ML : Hello, Currently doing a official upstream packaging for nnn [1] on OBS [2], I built a Debian file tree (with .rules, .control...), but I encountered a problem : The nnn package has two dependencies, which has totally different name depending on the OS version Adding an override for the debian.control variables in debian.rules like i would do on any Debian-based system :     derives_from_ubuntu := $(shell (dpkg-vendor --derives-from Ubuntu && echo "yes") || echo "no")     override_dh_gencontrol:     ifeq ($(derives_from_ubuntu),yes)             dh_gencontrol -- '-Vdist:Depends = libncursesw6 | libreadline8'     else             dh_gencontrol -- '-Vdist:Depends = libncursesw6 | readline-common'     endif Would make osc yell a     dpkg-deb: error: failed to open package info file 'debian/nnn/DEBIAN/control' for reading: No such file or directory (full log: [3]) But it does build fine with only one OS in mind Is there a way to fix this?
