Chirp no permission for "/dev/ttys0/"

Im trying to use Chirp to program my Icom IC-2820h, i get this error message when i try to read from the radio:

[Errno 13] could not open port /dev/ttyS0: [Errno 13] Permission denied: ‘/dev/ttyS0’

Im still a noob on linux and im getting really frustrated.

Try adding your user to the uucp group:

sudo gpasswd -a $USER uucp

Log out then back in again for the change to take effect.
