You are running a yum command or running a script on a RHEL server. You get this prompt:
"==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-units ===
Authentication is required to manage system services or units.
Authenticating as: Cloud User (ec2-user)
What do you do to troubleshoot this prompt as no password seems to work?
Cancel out of the prompt. Re-run the command but this time with "sudo " in front of it. Alternatively you could run "sudo su -" to assume the root user. But it would be best to use "sudo " in front of the command you were trying to run.
