I purchased an arduino compatible board ( Seeduino Lotus ) and I tried to install the Arduino IDE using the guide from the site. The example had the version 1.6.10. After I download it and unzip it I try to use the Terminal to install it. There this error shows up : " rm: cannot remove '/usr/local/bin/arduino': No such file or directory Removing symlink failed. Hope that's OK. If not then rerun as root with sudo. " Does anyone have an idea on how to fix it?
