Vermutlich ist der User nicht Mitglied der Gruppe "dialout"

Lösung:
sudo usermod -aG dialout <USER>

folgendes :

(base) rfr@rfr-ThinkPad-P17-Gen-2i:~$ sudo usermod -aG dialout arduino
usermod: user 'arduino' does not exist
(base) rfr@rfr-ThinkPad-P17-Gen-2i:~$ sudo usermod -aG dialout rfr
(base) rfr@rfr-ThinkPad-P17-Gen-2i:~$ arduino

irgendwie verstehe ich diese Fehlermeldungen meines Rechners nicht 
wirklich.
