Bug#670131: AttributeError: 'Version' object has no attribute 'policy_priority'

Package: unattended-upgrades
Version: 0.76.2
Severity: grave
Justification: renders package unusable

Hi,

I upgraded u-a on one 32-bit server to test if another problem is fixed and
found that it doesn't work anymore:

(on this system I do many u-a tests, that's why it has many packages blacklisted)

Thanks
