I am new to linux and ROS. I tried to install the ROS following http://wiki.ros.org/indigo/Installati... . At the step of sudo apt-get install ros-indigo-desktop-full, I get below messages. I cannot install ros-indigo-perception even if i go install all the depends of it. I tried to solve this by sudo apt-get install libsdformat1 , this did not help this situation.

My environment is followings; Distributor ID: Ubuntu Description: Ubuntu 14.04.4 LTS Release: 14.04 Codename: trusty

Thank you so much for your help in advance.

If you've installed all of the dependencies for ros-indigo-perception but it doesn't install, what error do you get when trying to install it?
