I have problem with uploading Arduino program to my Arduino Uno Wifi device through USB interface on my Ubuntu 18.04.1 LTS. After initiating upload process I get this error:

avrdude: ser_open(): can't open device "/dev/ttyUSB0": Permission denied

I already tried to solve this problem by common ways like changing user permissions on this interface and adding logged user to dialout group with these commands:

sudo usermod -a -G dialout cmaa
sudo chmod a+rw /dev/ttyUSB0

None of these commands solved my problem and error message from Arduino IDE remains the same. Do you have any suggestions how to solve this? Thanks in advance.
