I installed Arduino: 1.6.12 (Linux), Board:"Arduino Nano, ATmega328" on UBUNTU 16.04. I can't start: In get the message:
fork/exec /home/ad/Downloads/arduino-1.6.12/tools-builder/ctags/5.8-arduino10/ctags: permission denied
Aunt Google is always your friend:
On Linux, the Uno and Mega 2560 show up as devices of the form /dev/ttyACM0. These are not supported by the standard version of the RXTX library that the Arduino software uses for serial communication. The Arduino software download for Linux includes a version of the RXTX library patched to also search for these /dev/ttyACM* devices. There's also an Ubuntu package (for 11.04) which includes support for these devices. If, however, you're using the RXTX package from your distribution, you may need to symlink from /dev/ttyACM0 to /dev/ttyUSB0 (for example) so that the serial port appears in the Arduino software.
Run:
sudo usermod -a -G tty yourUserName
sudo usermod -a -G dialout yourUserName
Log off and log on again for the changes to take effect.
Sorry, but that's not the problem. The message is:fork/exec /home/ad/Downloads/arduino-1.6.12/tools-builder/ctags/5.8-arduino10/ctags: permission denied.
Same error when installing 1.8.5 today. I don't think the extraction set permissions on the files correctly, or they weren't correct in the archive - I had to make install.sh executable to run the installer. I installed 1.8.4 instead and the error went away.
