Cannot Sudo Su Anymore

[Devin Dixon]

I am not sure this goes in here but this morning for my VM instance when I connect via the web console ssh, and I type 'sudo su', it requires me have entered a password- which is new and preventing me from making changes. Has anyone else had this sudden change/problem?

As per this article and this article I would recommend try to modify /etc/sudoers and then try again to run 'sudo su' command to see if that fixes the issue or not? if not then provide me details regarding the operating system as this issue is related towards the operating system.
