gandi-cli name suggests it's not providing public module and thus no "public" requires.txt. If you want dh_python3 to read dependencies from a random file - make sure dh_python3 knows which one it should use: override_dh_python3: dh_python3 --requires path/to/file_with_deps.txt -- GPG: 1D2F A898 58DA AF62 1786 2DF7 AEF6 F1A2 A745 7645
