[buildd-tools-devel] Bug#882056: sbuild: Benign failures when sbuilding to ubuntu 14.04

[Dima Kogan]

Package: sbuild
Version: 0.73.0-4
Severity: wishlist

This has more to do with Ubuntu than Debian, but it'd be really nice if
it was fixed.

Running an sbuild to build packages in an ubuntu 14.04 chroot from
Debian/sid (normal build; no cross-build or multiarch or anything) I see
these issues:

  +-------------------------------------+
  | Install package build dependencies  |
  +-------------------------------------+


  Setup apt archive
  -----------------

  Merged Build-Depends: debhelper (>= 9), mrbuild (>= 0.51), dh-python, python-all-dev, libminimath-dev, libdogleg-dev, libopencv-calib3d-dev, python-numpy
  Filtered Build-Depends: debhelper (>= 9), mrbuild (>= 0.51), dh-python, python-all-dev, libminimath-dev, libdogleg-dev, libopencv-calib3d-dev, python-numpy
  grep: debian/control: No such file or directory
  /usr/bin/pkgsanitychecks: Error: not in source package directory
  /usr/bin/pkgstripfiles: Error: not in source package directory

These are scary-looking, but benign errors. Apparently ubuntu's dpkg-deb
tool is a shell script (unlike the ELF executable in Debian). Sbuild is
trying to "dpkg-deb build dir something.deb". The directory dir contains
only a DEBIAN subdirectory, but ubuntu's dpkg-deb is trying to grep
debian/control. Maybe this has nothing to do with sbuild.

These prints happen a few times through the build.

Second issue is that the dose3 invocation fails to report on the broken
dependencies. The log shows this:

  Preparing to unpack .../sbuild-build-depends-dose3-dummy_0.invalid.0_amd64.deb ...
  Unpacking sbuild-build-depends-dose3-dummy (0.invalid.0) ...

  report:

  total-packages: 0

It'd be good to at least print more useful things when it fails this
way.

There were a few more problems for which I have patches... in the
imminent bug report.
