Hello,
I have installed Raspbian Stretch at my RPi3 and the ros_comm for the ROS Kinetic package (since it was the recommended one from the ros wiki). However, when I try to install any package the message I receive is "E: unable to locate package" . For example, I type at the terminal "sudo apt-get install ros-kinetic-usb-cam" and the message I receive is the above. Any suggestions about what I am doing wrong?
----------
Update:
I have followed the instructions from [this site](https://wiki.ros.org/ROSberryPi/Installing%20ROS%20Kinetic%20on%20the%20Raspberry%20Pi):
$ rosinstall_generator ros_comm --rosdistro kinetic --deps --wet-only --tar > kinetic-ros_comm-wet.rosinstall
$ wstool init src kinetic-ros_comm-wet.rosinstall
