pycentral crashed with AttributeError in prepare()

[Srik]

It give me this crash trying to install via synaptic a "onboard" update (0.91 version).

It appears an error windows with:

E: /var/cache/apt/archives/onboard_0.91_all.deb: il sottoprocesso pre-installation script ha restituito un codice di errore 1

In english should be:
E: /var/cache/apt/archives/onboard_0.91_all.deb: the subprocess pre-installation script gave an error code 1
