Sources

The sources setting is used to configure additional sources from which to install packages. All sources configured using this approach must be signed and the signing key must be available online:

sources:
  apt:
    - name:            # The name of the source - used for filenames
      key_url:         # The URL from which to fetch the signing key
      dearmor: true    # Whether to automatically dearmor the signing key
      deb:             # The DEB line
        url:           # The URL for the DEB line
        distribution:  # The distribution for the DEB line
        component:     # The component for the DEB line

The name is used for generating filenames, thus it must be unique within the configuration.
