I fix that /etc/sudoers
near line 23 error by using pkexec visudo
command. But I don't know the reason. Can any one tell me the reason? And how to prevent these type of error in future?
My File Like this:
#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.

I can Fix this problem by deleting Last Line. But Don't know the reason.
