Title:
  apt  prints wrong error message when installing broken package

Status in “apt” package in Ubuntu:
  Confirmed
Status in “apt” package in Debian:
  New

Bug description:
  Universe contains broken packages for amd64 (and it is not the subject of this
  bugreport), and apt refuses to install them:
  apt-get install konq-plugins
  ............
  The following packages have unmet dependencies:
    konq-plugins: Depends: kdelibs4 (>= 4:3.3.2-1ubuntu8) but it is not going to
  be installed
                  Depends: konqueror (>= 4:3.3.2) but it is not going to be installed
                  Depends: libkonq4 (>= 4:3.3.2) but it is not going to be installed
                  Depends: ark but it is not going to be installed
  All 4 packages are already installed and have versions larger than necessary.
  The real problem is following:
  apt-get install konq-plugins konqueror ark
  ............
  The following packages have unmet dependencies:
    kdelibs-data: Conflicts: konq-plugins (< 4:3.3.99) but 4:3.3.2-1ubuntu1 is to
  be installed

  The first error message is very misleading. It will be more user-friendly to
  tell about conflict on the first request.
