Trying to tweak my sudo configuration

so I am trying to tweak my sudo configuration(sudo visudo -f /etc/sudo.conf) but unfortunately the following errors appeared ???

/etc/sudo.conf:16:22: syntax error
Plugin sudoers_audit sudoers.so error_recovery=true
                     ^~~~~~~~~~
/etc/sudo.conf:81:22: syntax error
Set disable_coredump false
                     ^~~~~
/etc/sudo.conf:123:41: syntax error
Debug sudo /var/log/sudo_debug all@debug, all@crit, all@err, all@warn, all@notice
                                        ^
/etc/sudo.conf:124:50: syntax error
Debug sudoers.so /var/log/sudoers_debug all@debug, all@crit, all@err, all@warn, all@notice
                                                 ^

Please note that i tried reading the manual of sudoers(5) and sudo.conf(5) but nothing helped with these errors

>Solution :

visudo is not intended for editing sudo.conf. It works only with sudoers file (and files using sudoers syntax).

For sudo.conf use any editor, for example :

sudoedit /etc/sudo.conf
