Auditd Service

[agentsofshield]

Hi,
I'm trying to run the auditd service with rules based on this Best Practice on Ubuntu 16.04 and i'm having some troubles-
I started with installing the auditd package with the command: "apt-get install auditd audispd-plugins".
Next, I switched the /etc/audit/audit.rules with my audit.rules file
And finally, I restarted the auditd service: "services auditd restart"

The problem:
When I'm running the "service auditd status" command I have this message-
Active: active (running) since ......
Process: 3728 ExecStartPost=/sbin/auditctl -R /etc/audit/audit.rules (code=exited, status=1/FALIURE)

Please help me find the right solution.
Thank you,
