Hi Brian, Jonathan,

It seems that packages from Debian (the ones in Bionic) are not compatible with Ubuntu ones (in Artful and before) :-/

Any idea what's the best solution? I think the ones in Debian had some issues that were affecting user experience at some points. Maybe the quickest is a revert to the Ubuntu packages with minor changes?

Best regards,
Matt
