Package arduino trusty (14.04LTS) (electronics): AVR development board IDE and built-in libraries If you still need help using your Arduino board, contact us.As we know Arduino has non-official Snap which can access serial ports only if installed as classic (but not indicated in snap find output): $ snap find arduinoĪrduino-mhall119 1.8.5 mhall119 - Arduino IDEĪrduino packages from repositories are outdated: If the process still doesn’t stop, you can use add the -9 flag to force it to quit: kill -9 If you can’t locate the source of the processs, you can terminate the process using the kill command. Using the process name or path may be able to find and close an application that’s running the process. You can use this command: ps -o ppid= | xargs ps Note: In some cases, the parent process may be more informative. In this example, an instance of Arduino IDE is using the port. In this case the resulting output was: ~ % ps 13854ġ3854 - 5:28.07 /home/username/Downloads/arduino-ide_2.0.0-beta.2_Linux_64bit To get more information about the process, use the ps command: ps We can get more info with this command (replace with the PID in your input): The second value, in this case 19772, is the Process identifier (PID). This is because another instance of the IDE is running with the Serial Monitor open. The first value returned is the process name, which in this case was java. If there is a process using the port, the output may look like this: lsof /dev/ttyACM0ĬOMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME Input the following command, replacing with the port name for your board. ![]() Look for it in your launcher, or try the Ctrl + Alt + T keyboard shortcut (available on most Linux systems). Open your computer’s command line application (often referred to as shell, terminal, console, prompt or various other names). It will usually start with /dev/tty, for example, /dev/ttyACM0. The port name may appear in the error output, but you can also see it in the Tools > Port menu. Identify the name of the port you’re trying to access. To add your user to the group, enter the following command in the terminal, replacing with the group name from the previous step, and with your username: sudo usermod -a -G Īnother cause of errors are other processes that are using the port. Take note of the group name in the response: crw-rw- 1 188, 0 5 apr 23.01 In Tools > Port, note the name of the port your board is connected to, such as dev/ttyACM0 or similar. If the group wasn’t found, or if you still get an error, the dialout group may have a different name. Restart your computer for the changes to take effect. By adding your user account to this group you will have the necessary permissions for Arduino IDE to communicate on the serial ports.Įnter the following command, replacing with the name of your account. Most Linux configurations have a dialout group for full and direct access to serial ports. If you experience this issue, see Fix udev rules on Linux.
