I am trying to install ROS on ubuntu 12.04 to use it with both gazebo and morse.

I first installed ROS fuerte, but the setup.* files were not created in /opt/ros/fuerte. So I removed ROS fuerte and tried to install ROS hydro. when typing sudo apt-get install ros-hydro-desktop-full an error occurred:

user@user-SATELLITE-L750:~$ sudo apt-get install ros-hydro-desktop-full [sudo] password for user: Reading package lists... Done Building dependency tree
Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: ros-hydro-desktop-full : Depends: ros-hydro-simulators but it is not going to be installed E: Unable to correct problems, you have held broken packages.

How can I resolve this ?

thanks in advance

I did what you said but it does not work, always the same error for ROS Hydro:/

After that I reinstalled ROS fuerte and setup.* where finally created.

Thank you :)

Hi djou

please try sudo apt-get upgrade which will try to solve your problems.

Try it all again by first cleaning and reinstalling later:

sudo apt-get remove ros-hydro-desktop-full
sudo apt-get clean
sudo apt-get autoclean

sudo apt-get update
sudo apt-get install ros-hydro-desktop-full
