ros jade and gazebo 5.0 migration problem

edit

Hello, I am trying to upgrade from ros indigo to ros jade. I followed the following procedure

sudo apt-get get remove ros-indigo-desktop-full

then

sudo apt-get get install ros-jade-desktop-full

However, when I am trying to launch a simulation with gazebo I obtain the following error

/opt/ros/jade/lib/gazebo_ros/gzserver: 22: .: Can't open /share/gazebo//setup.sh

/opt/ros/jade/lib/gazebo_ros/gzclient: 17: .: Can't open /share/gazebo//setup.sh

[gazebo-2] process has died [pid 5171, exit code 2, cmd /opt/ros/jade/lib/gazebo_ros/gzserver -e ode /home/mago/Projects/2015a_Nicastro_HeterogeneousMultirobot/src/uav/worlds/vtol.world __name:=gazebo __log:=/home/mago/.ros/log/0b588c00-6078-11e5-b34f-f04da268d7ae/gazebo-2.log]. log file: /home/mago/.ros/log/0b588c00-6078-11e5-b34f-f04da268d7ae/gazebo-2*.log

Apparently it can't find the file /share/gazebo//setup.sh
I noticed the double slash, therefore I tried to search the setup.sh file manually. However, the command

ls /usr/share/ | grep gazebo

gives

gazebo-3.0

gazebo-5.0

Moreover, in the "gazebo-5.0" folder there is no file "setup.sh"

I think something went wrong during the installation, I tried to remove everything and reinstall but without success. Can anyone help me?

EDIT: I tried the workaround described here, but apparently I have libgazebo5-dev already installed.
