Sudden issues with pki role

Hi, I just noticed that the pki config on a server got skewed. Our pki config has always worked fine. On trying to run it now with $ debops -v service/pki -l affected.server I get: =================== TASK [cron : Manage cron environment variables] * fatal: [server.name]: FAILED! => msg: |- The task includes an option with an undefined variable. The error was: dict_keys object has no element 0 The error appears to be in '/home/username/.local/share/debops/debops/ansible/roles/cron/tasks/main.yml': line 89, column 3, but may be elsewhere in the file depending on the exact syntax problem. The offending line appears to be: - name: Manage cron environment variables ^ here =================== But obviously I have never edited this file. To test another role, I tried running the service/nginx role, which finishes fine. How do I get the pki role working again? Any suggestion is welcome. Jason
