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

E: Sub-process /usr/bin/dpkg returned an error code (1)

libsdformat-dev and libsdformat1 seem to conflict:

The relevant versions:

$ apt-cache policy libsdformat-dev

libsdformat-dev:

libsdformat1:

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
