I am having issues uploading to my Arduino from the IDE on Ubuntu 18.04. The error message I have received is:

Arduino: 1.6.10 (Linux), Board: "Arduino/Genuino Uno" avrdude: ser_open(): can't open device "/dev/ttyUSB0": Permission denied

I have checked other questions similiar to this one and have tried adding myself to the dialout group running:

sudo usermod -a -G dialout username

and added permission to write: sudo chmod a+rw /dev/ttyUSB0

After, when I run: ls -l /dev/ttyUSB0

I get: crw-rw-rw- 1 username dialout 188, 0 jūl 2 16:09 /dev/ttyUSB0

However,I still get the same error message from the IDE.

Any help would be greatly appreciated!
