I'm trying to upload a file on a anet printer but I receive the error: "avrdude: ser_open(): can't open device "/dev/ttyUSB0": Permission denied"

I've tried all the tutorials: https://www.arduino.cc/en/Guide/Linux https://arduino.stackexchange.com/questions/21215/first-time-set-up-permission-denied-to-usb-port-ubuntu-14-04

My user is in the dialout group, I've logged out after changing the permission but nothing change.

Any help?
