New Relic plugin setup error

We tried integrating the NewRelic agent plugin and encountered error with unpacking the .deb file.
So I forced over-write with dpkg -i --force-overwrite /var/cache/apt/archives/nginx_1.9.6-1~precise_amd64.deb

And ran the command apt-get install nginx again.
Attached is the nginx-nr-agent.ini file and screenshot of the error.

Any help is appreciated.
