This issue seems to marked as "fix released" under Trusty, but I am seeing the issue (or one very similar). I have a brand-new SSD drive that I've put into an external USB enclosure and I am trying to install 14.10 onto it.
When I click on "Erase Disk" (the only apparently available option) after authorizing, I see this error message: 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' -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1294877 Title: Error erasing device: Unknown or unsupported erase type `' To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1294877/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
