Errors while installing Ros-jade

edit

i got an error while installing Ros -jade into Ubuntu 15.04. I followed instructions on this website(link text). I've done up to "$sudo apt-get update"(1.4: Installation ). But after entering command "$sudo apt-get install ros-jade-desktop-full", i got an error "E: Sub-process /usr/bin/dpkg returned an error code (1)"

What should I do?
