Ceph » ceph-volume

This doesn't happen all the time, and I've not been able to replicate. At the very least we should export the environment variable in APT systems so that there is no need to require a "front end".

TASK [ceph-common : configure ceph debian development repository] **************
task path: /tmp/tox.fKXrNZj3r4/xenial-filestore-single_type_dmcrypt/tmp/ceph-ansible/roles/ceph-common/tasks/installs/debian_dev_repository.yml:8
fatal: [mon0]: FAILED! => {
    "changed": false
}

MSG:

Failed to auto-install python-apt. Error was: 'debconf: unable to initialize frontend: Dialog
debconf: (Dialog frontend will not work on a dumb terminal, an emacs shell buffer, or without a controlling terminal.)
debconf: falling back to frontend: Readline
E: Sub-process /usr/bin/dpkg returned an error code (2)'

    "state": "present" 
}

The environment variable should go into the tox.ini where other environment variables are set:

DEBIAN_FRONTEND=noninteractive
