[ubuntu-dev] Bug#894504: backportpackage: sbuild creates .changes for release rather than release-backports

[Christopher Hoskin]

Package: ubuntu-dev-tools
Version: 0.162
Severity: normal

Dear Maintainer,

Using backportpackage with the -b and --builder=sbuild options produces a .changes file for release rather than release-backports.

e.g.

backportpackage -b -w build --builder=sbuild --destination=stretch --suffix=~bpo9+1 dh-golang

cat build/buildresult/dh-golang_1.34~debian9.0.1~bpo9+1_amd64.changes | grep Distribution
Distribution: stretch

This appears to be different to the behaviour with --builder=pbuilder. I think pbuilder uses the release specified in debian/changelog to produce the .changes file, whereas sbuild overrides this with the option passed to it in --dist.

If I try instead to run:

backportpackage -b -w build --builder=sbuild --destination=stretch-backports --suffix=~bpo9+1 dh-golang

Then I get the message:

dpkg-source: info: extracting dh-golang in dh-golang-stretch-backports
dpkg-source: info: unpacking dh-golang_1.34.tar.xz
backportpackage: Error: Unknown release codename stretch-backports

One possible solution would be to append -backports to the release passed to sbuild via --dist. The user would then need to have a chroot with a name like $release-backports-$arch-sbuild, $release-backports-sbuild, $release-backports-$arch or $release-backports. Alternatively the chroot name could be specified to sbuild separately with the --chroot option.

Or, backportpackage could be changed to accept release-backports as a destination.

Thanks.
