Certbot on CentOS seems to have broken down

[andreby]

This happens when I try to deploy cpauth on a freshly created CentOS VM. I seems as though something has changed in the packaging of the certbot packag, and not all of its dependencies are installed.

TASK [icos.cpauth : Install SSL certificate] ***********************************
fatal: [centos]: FAILED! => {
    "changed": true, 
    "cmd": [
        "certbot",

}

STDERR:

Certificates are not requested anymore on test VMs and installation works in production.
