I get this massage: usermod: Permission denied. usermod: cannot lock /etc/passwd; try again later after trying to add myself to audio group by: usermod -a -G audio USERNAME.

I would be grateful for any help.

    Did you try prefacing the command with sudo? – J. Starnes Jan 3 '18 at 2:06

    sudo usermod -a -G audio USERNAME will work – Harsh Patel Jan 3 '18 at 5:25

You need to run usermod as root, you can do this with sudo:

sudo usermod -a -G audio USERNAME
