Hi,

I've attempted to upgrade from ROS Hydro to ROS Indigo after upgrading my Ubuntu 
Precise to Ubuntu Trusty. However, I'm getting conflicts after 
installing ros-indigo-desktop-full. 

Quick summary:

$ apt-get -f install
The following NEW packages will be installed:
  libsdformat-dev{a} libsdformat1{a} 
The following partially installed packages will be configured:
  gazebo2 ros-indigo-desktop-full ros-indigo-gazebo-plugins ros-indigo-gazebo-ros ros-
indigo-gazebo-ros-pkgs ros-indigo-simulators 


eggie@Idefix:~$ sudo apt-get -f install

libsdformat-dev and libsdformat1 seem to conflict:

As far as I can tell, it seems to prefer the Ubuntu packaged libsdformat over the ROS 
packaged sdfformat, I suppose this may be the source of the problem?

However, running:

apt-get install libsdformat1=1.4.11-1osrf1 libsdformat-dev=1.4.11-1osrf1

does not solve the problem and results in the same conflict.

Any suggestions?

Thanks,

Egbert
