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
