Quack,
First, Steinar, I had the same crash and you need to exclude
'inline-signing yes' if your zone uses 'allow-update' or
'update-policy'. A proper error message would have been welcome indeed.
I was also struck by this breakage and my whole infra was down because I
use unattended-upgrades + needrestart. This really has no place in a
security updates but clearly upstream made a mistake. I would be in
favor of a rollback to the previous version but maybe by the time it's
already too late.
Regards.
