Arduino IDE Permision Denied For Upload, Ubuntu 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!
As mentioned on the official guide for Linux, you need to run

sudo usermod -a -G dialout &lt;username&gt;

with the &lt;username&gt; replaced with the username of your system.
After running this, log out and log in and you should be good to go.
