software update ends with 'exceptions.AttributeError'>: 'Transaction' object has no attribute 'pktrans'

[Geoffrey de Kleijn]

When updating 103 packages this morning, the aptdaemon crashed after new packages had been installed and configured. I have updated packages last night as well, without any problems. Last nights' update was followed by a system reboot to update to kernel.
