We describe here one way to work with the package sources. Initialize cowbuilder: git-pbuilder create Optionally update cowbuilder: git-pbuilder update Clone the repository: git clone git@github.com:Yubico/python-yubico-dpkg.git Build the package: gbp buildpackage --git-pbuilder --git-pbuilder-options=--twice If all goes well, you should have newly built packages in ../. Update the package to a new upstream release (don't forget debian/changelog): gbp import-orig /path/to/new-release.tar.gz
