Basically what happens is that the patch 'ostree-stub.patch' produces an empty file 'ostree_src.go' and the compiler doesn't accept an empty Go file.
My affirmation WRT the path can be confirmed by reading the patch itself [2] or just applying it. [2] https://salsa.debian.org/go-team/packages/golang-github-containers-image/blob/master/debian/patches/ostree-stub.patch#L1104 The error reported by the compiler is (see full buildlog below): can't load package: package github.com/containers/image/ostree: obj-x86_64-linux-gnu/src/github.com/containers/image/ostree/ostree_src.go:1:1: expected 'package', found 'EOF' On Mon, 2019-04-29 at 07:29 -0400, Reinhard Tartler wrote: > I'm having a hard time understanding what issue you are facing with and what > you mean fix "fix manually".

I'm using none of them, I'm building "the hard way": in a container (from Docker base image debian:sid-slim) with a script that runs the individual steps and builds with 'dpkg-buildpackage'. It should be possible to build these packages this way, right? It usually works. I prefer not to use too much magic (although using containers involves per-se some magic) to better understand what's going on. What I meant with "fix manually" is executing "rm ostree/ostree_src.go" right after patching and before building. I don't know if the 'magic' of any of the mentioned tools is just silently fixing the issue for you and that's why you are not facing it... > In any case, a full buildlog, similar to what I attached, could be helpful. > If English is a language barrier, try explaining in German. I don't think that it's a language barrier. But possibly an expertise barrier: my expertise on building Debian packages (specially for Go) is not as extensive as yours :-) --- dpkg-buildpackage: info: source package
