How to add user to group (dialout)

I'm having an issue add my user to the dialout group that I need to have permission on usb serial port for arduino developpment. I tried this

sudo usermod -a -G dialout <username>

sudo usermod -a -G dialout <username>

and it doesn't work.

groupadd adds groups though take a look at the groups/ that own your USB device just to make sure

I tried groupadd and it told me that the group already existed but I found a solution

sometimes the groups are named differently run as root?

I found out that it was linked to some container stuff, and I used :

grep "^dialout:" /usr/lib/group | sudo tee -a /etc/group > /dev/null
sudo usermod -aG dialout <username>

grep "^dialout:" /usr/lib/group | sudo tee -a /etc/group > /dev/null
sudo usermod -aG dialout <username>

and now when I use

groups

groups

I have

<username> wheel dialout

<username> wheel dialout
