Hi, all:

I'm using Ubuntu 14.04:

:/$ lsb_release -a

No LSB modules are available.

Distributor ID: Ubuntu

Description: Ubuntu 14.04.2 LTS

Release: 14.04

Codename: trusty

Strictly followed http://wiki.ros.org/indigo/Installation/Ubuntu, but failed to install it. Does anybody know why and how to have ROS successfully installed?

.....$ sudo apt-get install ros-indigo-desktop-full

Reading package lists... 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-indigo-desktop-full : Depends: ros-indigo-desktop but it is not going to be installed

Depends: ros-indigo-perception but it is not going to be installed

Depends: ros-indigo-simulators but it is not going to be installed

E: Unable to correct problems, you have held broken packages.
