Thanks for your bug report. Could you please add the output of '/var/log/syslog' and '/var/log/partman' if possible? You can read about attaching log files here:

Thanks in advance.

Thanks for your report. It's not entirely clear why dpkg failed here, but ubiquity's poor response to this event is bug 69470.
