Ignition Gazebo crashes on start (works in humble but not galactic)

I just created a new environement and installed ros-galactic-ros-ign-gazebo.

The installation went fine but running ign gazebo generate some errors in the console and the application crashes a second later.

Segmentation fault (Address not mapped to object [(nil)])

It seems that it failed to locate the ODE and Ogre 2 shared libs. I don't know if they are not installed or if its just the LD_LIBRARY_PATH that is not set correctly in order for the dynamic linker to find them.

Start by reproducing ign gazebo in the reported ROS Galactic environment and inspect whether libode.so.0.16.2 and the Ogre2 shared library are installed and discoverable through LD_LIBRARY_PATH. The issue is done when the missing-library errors are resolved and the application starts without the renderer crash.
