It seems so.
The History feature and history command are not working. And the /etc/sudoers file isn't producing the outcome I expect from it after I modify it.
(add a new user or command to it)
When I run sudo telinit 1, it gets stuck there and I have to hard boot to my way out. I can see couple of error messages.
Of course, this is just a machine I am using for learning ubuntu, and is not a production machine.

And I did run that command as previously suggested.

touch /forcecheck
reboot

Well, this is a possible clue as to the source of the error messages you are getting.
Can you post, in as much detail as possible, exactly what modifications you have made to the /etc/sudoers file?
Where you following a tutorial for editing the /etc/sudoers file? If so, can you post a link to it?
Where you getting these errors before you modified the /etc/sudoers file??
Have you tried removing the modifications that you have made to the /etc/sudoers file, and restoring the file to it's pristine, unedited state? Do these errors disappear after you remove these modifications???

It is always a good practice to backup any system configuration files before you edit them.
Here is a tutorial that may help you to restore the /etc/sudoers file if you need it: http://psychocats.net/ubuntu/fixsudo

Yes, this is a link to my other thread, on this forum about /etc/sudoers file.

http://www.linuxquestions.org/questi...mmands-874010/


and this is the page I was following when I modified my sudoers file.

https://help.ubuntu.com/community/Sudoers

Oh, I am not worried about my /etc/sudoers file as it was before.
I can easily restore it to the original form, but just discouraged that I can't learn how to add new users to the list of sudoers and give them commands to run.
