Bug 243039 was linked to this bug. I can confirm what @jfhavet is saying that with usb-creator-gtk 0.2.56.1 which is the most recent version under Ubuntu 14.04, this issue persists. When clicking the "Erase" button the following error pops up :
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' I can also confirm that @jfhavet's workaround works well. Under English localized Ubuntu 14.04 the process is : 1 Open unity dash 2 Search for "Disks" or "udisksd" and launch "Disks" 3 Select your usb stick in the peripherals list 4 Click the little gears then select "Restore disk image..." 5 "Restore" Ubuntu iso image onto your stick -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1273925 Title: usb-creator-gtk fails to finish erasing a usb drive To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usb-creator/+bug/1273925/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
