Hello, I am trying to edit my sudoers file on my Ubuntu machine but I am unable to do this. When I run the command sudo visudo I get a screen as the one shown in my attachment. Once I add a line in the file I am not able to save it. Can someone let me know what I need to do? Thank you.

What error message do you get when you try to save it?

Press Ctrl and X, it should then prompt to save changes. Once you choose Yes, it should give an error message as to why it cannot save.

Did you read the comments in the sudoers file (they are in the screenshot you posted):

#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#

According to that you should create a file in the folder /etc/sudoers.d/ in which you have your changes to the original sudoers file.
