automated installation failed: msg: No package matching 'redis-server' is available at TASK: [aggregator | Install REDIS]

Hi,

I am using automated installation for all in one manager on Debian 7 64bit server.
The script "ansible-playbook -i hosts site.yml" running okay until TASK: [aggregator | Install REDIS]
The error I got the error
TASK: [aggregator | Install REDIS] ********************************************
failed: [server.host.com] => {"failed": true}
msg: No package matching 'redis-server' is available

FATAL: all hosts have already failed -- aborting

PLAY RECAP ********************************************************************
to retry, use: --limit @/root/site.retry

server.host.com : ok=11 changed=1 unreachable=0 failed=1

The Debian 7 64bit server's build information is
Linux xsb-appmon 3.2.0-4-amd64 #1 SMP Debian 3.2.65-1+deb7u2 x86_64 GNU/Linux
I did install the redis-server (redis-2.8.19) manually and then ran the installation script . The error is the same.
Could you help me on this error?

resolved by manually installed redis-server on the aggregator
