Can't install ROS Tutorials

[acolello]

I am trying to learn ROS by completing the tutorials on the ROS website, but whenever I try to download any of their packages, by using sudo apt-get install ros-kinetic-ros-tutorials I receive the error E: Unable to locate package ros-kinetic-ros-tutorials . I get the same error whenever I try to download any other ROS package, even when I test it with something basic like sudo apt-get install roscpp.

I believe I have added the key to the ROS repositories because when I run sudo apt-key list I get this output:
/etc/apt/trusted.gpg

Any help I could get is appreciated.

@acolello you cannot expect to install normal computer stuff under a embedded platform. Those tutorials are not suitable for Erle-Brain.

If you still want to perform those tutorials under Erle-Brain (better doing it under you computer), you need to download the source-code and compile it.
