[Bug 917173] Re: lucid -> precise upgrade failed: Resolver failed to calculate the upgrade - dpkg-dev held back

[Launchpad Bug Tracker]

This bug was fixed in the package apt - 0.8.16~exp5ubuntu13.3

---------------
apt (0.8.16~exp5ubuntu13.3) oneiric-proposed; urgency=low

  [ Jean-Louis Dupond ]
  * Backport fixes from precise verison of apt, to fix multiarch upgrades
    from oneiric.
  * apt-pkg/depcache.cc:
    - prefer native providers over foreigns even if the chain is foreign.
      (LP: #850264)
  * cmdline/apt-get.cc:
    - ignore foreign architectures if we check if a provides has only one
      resolver as it's basically the same for the user, so no need to choose.
  * apt-pkg/deb/deblistparser.cc:
    - M-A: foreign packages provide for other archs, too

  [ Colin Watson ]
  * Include 0.8.16~exp5ubuntu13.1 patches.
  * apt-pkg/algorithms.cc: Iterate Breaks the same way as Conflicts, so that
    we resolve virtual package Breaks more effectively (LP: #922485).
  * apt-pkg/algorithms.{cc,h}: Use an int to represent resolver scores, not
    a signed short, because large upgrades can result in an overflow for
    core packages (LP: #917173).

Bug description:
  lucid to precise i386 daily upgrade testing

  Upgrade fails with "pkgProblemResolver::Resolve generated breaks, this
  may be caused by held packages."

  From apt.log
  Investigating (9) dpkg [ i386 ] < 1.15.5.6ubuntu4.5 -> 1.16.1.2ubuntu5 > ( admin )
  Broken dpkg:i386 Breaks on dpkg-dev [ i386 ] < 1.15.5.6ubuntu4.5 -> 1.16.1.2ubuntu5 > ( utils ) (< 1.15.8)
    Considering dpkg-dev:i386 29 as a solution to dpkg:i386 7205
    Upgrading dpkg-dev:i386 due to Breaks field in dpkg:i386
  Investigating (9) dpkg-dev [ i386 ] < 1.15.5.6ubuntu4.5 -> 1.16.1.2ubuntu5 > ( utils )
  Broken dpkg-dev:i386 Depends on libdpkg-perl [ i386 ] < none -> 1.16.1.2ubuntu5 > ( perl ) (= 1.16.1.2ubuntu5)
    Considering libdpkg-perl:i386 12 as a solution to dpkg-dev:i386 29
    Holding Back dpkg-dev:i386 rather than change libdpkg-perl:i386
