Package: debdelta
Version: 0.40exp
Severity: important
File: /usr/bin/debdelta

Hi!

Today while trying to run "debdelta-upgrade -v" I saw this:

debdelta-upgrade : E:Error, pkgProblemResolver::Resolve generated
breaks, this may be caused by held packages.

I have some packages on hold in aptitude (but not in dpkg) and it never
caused any kind of problem (actually debdelta also downloads the deltas
of the packages on hold in aptitude - #544582).

With a simple "aptitude full-upgrade":

=====
# aptitude full-upgrade

6)     xserver-xorg-input-synaptics
7)     xserver-xorg-video-intel    



Accept this solution? [Y/n/q/?]

So maybe this situation is somehow confusing debdelta?

Testing with only packages that are known to be correctly installable:

=====

But debdelta also complains:

=====
# debdelta-upgrade -d -v apt-file base-files bti bzr chromium-browser
  chromium-browser-inspector debootstrap dictionaries-common iceweasel
  iproute libatasmart4 libavahi-client3 libavahi-common-data

    return func(*args, **kwds)
  File "/usr/lib/python2.6/dist-packages/apt/cache.py", line 210, in upgrade
    self._depcache.upgrade(dist_upgrade)
=====

Or even more simple:

=====
# debdelta-upgrade -v apt-file
debdelta-upgrade : E:Error, pkgProblemResolver::Resolve generated
breaks, this may be caused by held packages.
=====

What can I do to help in debugging this, please?

Thank you!

Best regards,
Nelson
