Dear Maintainer,

   * What led up to the situation?

unattended-upgrade upgrading wpasupplicant (2:2.10-15) over (2:2.10-12).

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Executed "sudo unattended-upgrade" manually to force a major unattended
upgrade.

   * What was the outcome of this action?

Seems that the upgrade came through successfully, BUT:
During the process the following error was reported on the
terminal:

  [~]$ sudo unattended-upgrade
  [sudo] password for farblos:
  tar: .remove-on-upgrade /etc/dbus-1/system.d/wpa_supplicant.conf: Not found in archive
  tar: Exiting with failure status due to previous errors

I guess that this has to do with the first line of the config
file definition of the package:

  [~]$ cat /var/lib/dpkg/info/wpasupplicant.conffiles
  remove-on-upgrade /etc/dbus-1/system.d/wpa_supplicant.conf
  /etc/wpa_supplicant/action_wpa.sh
  /etc/wpa_supplicant/functions.sh
  /etc/wpa_supplicant/ifupdown.sh

More logs available on request.

   * What outcome did you expect instead?

No funny error messages.
