I recently purchased an Arduino Uno R3, and in my preparation for its delivery, I thought I would set up my computer to receive. I downloaded the .zip files of the new library and first tried the basic instruction to add, however in the Sketch>Add Library menu there is no selection for new zip library. I then tried the manual route, and it went pretty well, up until I attempted to extract the .zip file(s) in to /usr/share/arduino/libraries (the directory on my machine) and it told me that I did not have the correct permissions. If some one with a little more Ubuntu know than mine could assist me this would be wonderful.
