[Bug 1100900] Re: ia32-libs won't install unless I also install libgd2-xpm:i386

[Steve Langasek]

The libgphoto2-2 dependency on libgd2-xpm is correct; and since
libgd2-xpm and libgd2-noxpm conflict, you must have the xpm version of
both the i386 and amd64 versions of libgd2.  That makes this a bug in
graphviz, for preferring the noxpm version of libgd2.  We have taken
care to enforce libgd2-xpm as the preferred version for all packages on
the Ubuntu CD for reasons such as this; that should be extended to other
packages as well.

  ia32-libs won't install unless I also install libgd2-xpm:i386

Bug description:
  On Ubuntu 12.04.1 LTS installed using lxc (i.e. headless), doing
  $ sudo apt-get install ia32-libs
  fails with
  The following packages have unmet dependencies:
   ia32-libs : Depends: ia32-libs-multiarch

  $ sudo apt-get install ia32-libs-multiarch
  says
  The following packages have unmet dependencies:
   ia32-libs-multiarch:i386 : Depends: libgphoto2-2:i386 but it is not going to be installed
                              Depends: libsane:i386 but it is not going to be installed

  $ sudo apt-get install libgphoto2-2:i386 
  says
  The following packages have unmet dependencies:
   libgphoto2-2:i386 : Depends: libgd2-xpm:i386 (>= 2.0.36~rc1~dfsg) but it is not going to be installed

  And hey presto,
  $ sudo apt-get install libgd2-xpm:i386  ia32-libs
  says
  The following packages will be REMOVED:
    libgd2-noxpm libgraphviz-dev libgvc5 libmagick++-dev libmagickcore-dev libmagickcore4-extra libmagickwand-dev
  but works! 

  (Since my real need was to run the android sdk, I ended up installing a subset instead of the full-on ia32-libs, e.g.
    sudo apt-get install libc6:i386 zlib1g:i386 libstdc++6:i386
  but figured I'd mention the workaround here in case it helped others.)
