password plugin problem with chpasswd method

[boxyball]

I am trying to install RC 1.3.9 on Fedora 30.
I have gotten the password plugin to work in the past no problem.
I have followed all the directions and also added permissions in visudo.
But it is not working and I am seeing this in errors.log

PHP Error: Password plugin: Unable to execute sudo /usr/sbin/chpass-wrapper.py 2> /dev/null in /var/www/html/roundcube/plugins/password/drivers/chpasswd.php on line 47 (POST /?_task=settings&_action=plugin.password-save)

Thanks in advance for any help.
