Usermod: group 'dialout' does not exist

I am trying to upload to an ardiuno board and need to get permission to use the port for that and when I try to run this:

sudo usermod -a -G dialout <username>

but when I do that it returns with:

usermod: group 'dialout' does not exist

Thank you for your time

The equivalent group on Arch based distributions is uucp. Run below command to add your current user and then logout/login. Also see Users and groups - ArchWiki and Arduino - ArchWiki.

sudo usermod -a -G uucp $USER

Thank you
