Running the code I get an error on apt Cache

[jcourt2006]

Good day,
I run the code but I see the following fail:
[WARNING]: Updating cache and auto-installing missing dependency: python-apt
fatal: [192.168.60.6]: FAILED! => {"changed": false, "cmd": "apt-get update", "msg": "[Errno 2] No such file or directory", "rc": 2}
fatal: [192.168.60.4]: FAILED! => {"changed": false, "cmd": "apt-get update", "msg": "[Errno 2] No such file or directory", "rc": 2}
fatal: [192.168.60.5]: FAILED! => {"changed": false, "cmd": "apt-get update", "msg": "[Errno 2] No such file or directory", "rc": 2}

I don't understand why we use apt-get if we are using Centos servers. Maybe I have not do a step before.
Please help me
