Hi, I just installed Arduino on Linux Ubuntu. Tried to test it with "blink" example but have been unable to upload the sketch. My error message is : avrdude: ser_open(): can't open device "/dev/ttyUSB0": Permission denied Tried with three different Nano board. Any ideas?

Cant open device message on Linux
