    You can make this method of disabling IPv6 usage in GNU Linux based operating systems (Debian, Ubuntu and others) by putting the following into the /etc/sysctl.conf file:

    net.ipv6.conf.all.disable_ipv6 = 1

    Then either reboot or run ‘sysctl -a’ as root to enact it immediately via the sysctl.conf file entry.
    FYI,
