Hi, I recently came up with this 'issue' (not really an issue in fact, please read along) when I configured a Webmin panel on a CentOS 6.7 instance we use at work.
Thing is that the sudo tool provides a configuration flag to deny a command execution if it's not being invoked from a console. Originally this was thought as an additional security layer but ultimately proved to be more a nuisance than anything else and that's why Red Hat decided to switch it off by default on newer releases starting with RHEL 7 (I don't know starting at which Fedora release though). To disable this check launch visudo, look for "Defaults requiretty" and comment the line. I believe that you can accomplish the same by adding the entry to a file in /etc/sudo.d/ but I didn't test it myself.
