Unable to Install ROS Hydro on Ubuntu 12.04 Precise

[francis xavier]

Hi I have been trying to install Hydro but unable to do so. I am using Ubuntu 12.04 and already have groovy in it. When I tried doing a full desktop install I keep getting this error:

"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."

What can I do? I am still very new to ROS, am not very sure.

Hi Francis,

Please have a look at the solution provided for this same question on askubuntu.com.   I would try each suggested fix one at a time and after each, try running the ROS installation command again (sudo apt-get install ros-hydro-desktop-full).

Hi Patrick,

I managed to do a full desktop installation of Hydro. I installed and used aptitude instead of apt-get and it worked.

Kind regards,
Francis

Hi Francis,

That's good to hear and thanks for sharing the tip about using aptitude instead of apt.  I have often had dependency issues when using apt so I look forward to trying aptitude the next time I have trouble.
