Well, back to point, on Debian based Linux flavors this error can be a reason of broken sudo or easy term corrupted sudoers. Broken sudoers has multiple reason, most important are as below;

1. User must resides in the sudo or admin group and one should not remove it.
2. The /etc/sudoers file was altered to prevent users in sudo or admin group from elevating their privileges to that of root using sudo command.
3. Confirm if the correct permission (dr--r----- or 0440) are setup on /etc/sudoers.
