Unclickable port on Ubuntu 18.04 in Arduino IDE

Dear all, my Arduino has arrived :slight_smile:
The port on the app Arduino IDE is not clickable.

I have done these instructions on my terminal:

$sudo apt-get update
$sudo apt-get install ubuntu-make
$umake ide arduino
$sudo usermod -a -G dialout $USER
$sudo usermod -a -G tty $USER

The port is still not clickable (although the Arduino produices light when connected to the computer). What can I do next?
All advices are welcome.
Thank you!
Octave

Uninstall the version from the repository and next install the version from the arduino website.

I have done this and it is now functionnal!
THANK YOU I CAN NOW START HAVING FUN :))))))
