Comment 1 for bug 825704

could not retrieve logs; found them using Ctrl-Shift-F1 (via terminal) while error is on screen. need some way to copy logfiles to a safe place as they get deleted even on hard reset. might try to copy logfiles to filesystem root.

at the same time, found a workaround: unplugging the network cable seems to make Wubi/ubiquity skip over some steps which are responsible for this error.

yet, other errors pop up afterwards, see https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/825736
