Unknown Error from Startup Disk Creator – How to Troubleshoot

formatmp3startup-disk-creatorsystem-installationusb

I don't understand this error from the Startup Disk Creator:

org.freedesktop.DBus.Python.AttributeError: Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/dbus/service.py", line 707, in _message_cb
    retval = candidate_method(self, *args, **keywords)
  File "/usr/share/usb-creator/usb-creator-helper", line 218, in Format
    parent_dev = _get_parent_object(udisks, device)
  File "/usr/share/usb-creator/usb-creator-helper", line 49, in _get_parent_object
    parent = partition.get_cached_property('Table').get_string()
AttributeError: 'NoneType' object has no attribute 'get_cached_property'

What does this mean? I only want to erase the 2GB MP3 player in order to put the iso on there. The disk creator requires this step.

This is a known bug: https://bugs.launchpad.net/ubuntu/+source/usb-creator/+bug/1294877

There are several workarounds but the one that worked for me was to right click on the .iso in the file explorer and select 'Open With Disk Image Writer' and then 'restore' the ISO image to the selected USB device.
