avrdude: ser_open(): can't open device "/dev/ttyACM0": Permission denied
Not able to upload programs to the Arduino UNO.
Im using the 1.8.1 IDE on 32bit Ubuntu Mate 16.10 LTS.
I am able to select the port on Tools --> Ports but the IDE wont upload to the board, even simple LED blinking program dosent upload.
I have left a msg on the Arduino forum, I was thinking if there is a way in Mate to grant permissions to boards like the UNO.
