The sudo command runs 'echo' as root but the '>' redirection happens in your shell as your normal user. Try this instead: echo "deb http://files.freeswitch.org/repo/ubuntu-1604/freeswitch-1.6/ xenial main" | sudo tee /etc/apt/sources.list.d/freeswitch.list tee will send the line to both stdout and the file, and since it's run as root will overwrite the file with permission to do so.
