Dependency install failure: ros-diamondback-ros-tutorials

edit

Hi All,

I am using Ubuntu 10.10 and try to install ROS. I followed every step found on the website, but something is wrong at the last step. Any suggestions or hints would be appreciated.The output is as follows. (The Linux kernel is 2.6.37, and before I tried to install ROS, I had installed Matlab R2010b -- not sure if this is related, just FYI)

$ sudo apt-get install ros-diamondback-desktop-full
