I have deployed Ubuntu 12.04 on the Amazon Cloud and I am trying to install Nagios and Nconf, while following this guide. When I install the prerequisites, I get this error on installing mysql:

mmon_5.5.24-0ubuntu0.12.04.1_all.deb  404  Not Found [IP: 80]  
Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/m/mysql- 5.5/libmysqlclient18_5.5.24-0ubuntu0.12.04.1_amd64.deb  404  Not Found [IP:  80]  404  Not Found [IP: 80]  
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

ubuntu@ip-10-244-18-255:~$ security.ubuntu.com

As I am new to Ubuntu, can someone please give me an advice what am I doing wrong here?

Many thanks, Vancho.

Welcome to Ask Ubuntu! Did you forget to run sudo apt-get update? This is needed to refresh the package lists. –  gertvdijk Jan 17 '13 at 1:33
