Hi,
There is a validation Error for the Linux Configure Sudo task.
I added the user to wheel group and tested the sudo. Everything worked fine.
Yet, my task was failed with the message “- sudo access on App Server 1 is not configured properly”
I copied the steps I followed. See below

We trust you have received the usual lecture from the local System Administrator. It usually boils down to these three things:
#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.
