maybe you need to update your dkms?

[Gianfranco Costamagna (costamagnagianfranco)]

Steve, do you think this might be related to the new dkms changes? "required key missing" it seems...

[Steve Langasek (vorlon)]

Almost certainly related. Return code 30 strongly suggests a debconf error. I'm currently traveling and unable to look in detail, perhaps Matt can have a look in the meantime.

Status changed to 'Confirmed' because the bug affects multiple users.

Mathieu, what do you think about this issue?
