Just to let you know there was a large burst of Jade sourcedeb failures on Trusty. We started using an option for dpkg-buildpackage that turned out not to be available on trusty and older platforms causing the failures.
We’ve added a workaround for now and the farm should be working through the errors shortly. If you got an email in the last hour or so about a Jade sourcedeb on Trusty you can ignore it. There should be a back to successful email soon too.
