  Justification: FTBFS in wheezy on amd64
  
  Hi,
  
  During a rebuild of all packages in *wheezy*, your package failed to
  build on amd64.
 […]
  The following packages have unmet dependencies:
   sbuild-build-depends-backbone-dummy : Depends: libnode-uglify but it is 
  not installable
  E: Unable to correct problems, you have held broken packages.
  apt-get failed.
 
 Actually its an OR dependency:
 
  libnode-uglify | yui-compressor
 
 The package builds fine in a Wheezy amd64 pbuilder chroot (pulling
 yui-compressor), thus closing the bug. I just wanted to put some light
 on this issue: maybe the resolver used to perform the archive rebuild
 could be improved to avoid this kind of false positive.

Hi,

By default, sbuild ignores alternative build-dependencies (a | b) and
only uses the first package. that is to ensure reproducible builds, and
avoid situations where packages build against different b-deps on
different architectures. So the bug is valid, and should be fixed in
wheezy (and I'm not aware of the release team considering those failures
non-RC).

 I've tagged a few FTBFS on wheezy as unreproducible (because I didn't
 investigate why it failed ten days ago, or because I couldn't find an
 obvious reason), should I simply have closed them?

Did you Cc me? I have very little time for Debian recently, but try to
keep up with bugmail where I'm Cced.

Anyway, a good way to make progress is usually to provide a build log,
and a diff between my log and your log.

Lucas

Thanks for your quick answer, and thanks Jonas who was even quicker,
preparing a t-p-u right now.

No, sorry about that, those were #684833, #684837 and #684860. Cédric
already looked at the last one with the same result than me, and should
investigate again soon.

 Anyway, a good way to make progress is usually to provide a build log,
 and a diff between my log and your log.

Thanks for the tip, I'll try to have a second look at the first two,
following your advice.

Regards

David

OK, the first two look like bugs that will be easier to understand with
a diff (maybe a build-dep that was broken was fixed in the meantime?).
For the third one, I'm a bit more puzzled.

Note that I auto-retry builds before filing, so when I file a bug, it
means that the build failed twice in a row. This does not exclude chroot
configuration issues, or environment issues, but at least excludes all
random/cosmic rays problems.

Justification: FTBFS in wheezy on amd64

Hi,

During a rebuild of all packages in *wheezy*, your package failed to
build on amd64.

Relevant part:
 ┌──┐
 │ Install backbone build dependencies (apt-based resolver)
  │
 └──┘
 
 Installing build dependencies
 Reading package lists...
 Building dependency tree...
 Reading state information...
 Some packages could not be installed. This may mean that you have
 requested an impossible situation or if you are using the unstable
 distribution that some required packages have not yet been created
 or been moved out of Incoming.
 The following information may help to resolve the situation:
 
 The following packages have unmet dependencies:
  sbuild-build-depends-backbone-dummy : Depends: libnode-uglify but it is not 
 installable
 E: Unable to correct problems, you have held broken packages.
 apt-get failed.

The full build log is available from:

A list of current common problems and possible solutions is available at 
http://wiki.debian.org/qa.debian.org/FTBFS . You're welcome to contribute!

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.
