Arduino IDE on Pop OS 21.04

Using Arduino IDE 1.x
1

I have tried following the installation from https://www.arduino.cc/en/Guide/Linux

However, I get the following error when I run ls -l /dev/ttyACM*
ls: cannot access '/dev/ttyACM*': No such file or directory

It is the same result for ls -l /dev/ttyUSB*

The command sudo usermod -a -G dialout executed without error.

Due to this Tools -> Port option is disabled.

What do lsusb and dmesg say when you connect the board?

Forgot to ask, which board?

If the board disappears, there might be something wrong with the board. I doubt I can help you further.
