Uncaught Exception raised - No such File or Directory

[Kyle Knight]

Binary package hint: usb-creator

I have tried with multiple iso files (11.04 and 10.10) and this happens every time I try to create a USB startup disk. The prcoess gets to 99% and then ends with "An uncaught exception was raised: [Errno 2] No such file or directory. The pop up box only gives me the option to Quit.

Adding screenshot showing the install.py file in the correct directory....

Here is the screenshot of the very un-ubuntu error message.

Translation:
An uncaught exception has occurred
Errno 2 File or folder does not exist.

A proper Ubuntu error message should give more details as to which file or folder it is expecting.

This is clearly an authorization problem.

In order to debug
I started the program first with:

Running from the Ubuntu System menu.

What happens is I get 3 policy windows.
1 for starting the app
1 for mounting the usb disk
1 for writing the bootloader
then it fails.

so I tried from the comand line using:
usb-creator-gtk -s

This resulted in a pop up box saying installation of the bootloader failed, after this popup box a policy (see screenshot) window popped up asking for my password after the fact. By then it was too late, the installer had stopped.

then I tried with:
gksu usb-creator-gtk -s

This command made a successful disk.

So the issue I suspect is that the program is asking for authorization to late in the process.

I get the same error every time I try to create a bootable USB disk

An uncaught exception was raised:
[Errno 2] No such file or directory

I have the same problem on Kubuntu 10.10. When I look through the mailing lists, I find other reports for the same problem that go back to at least Kubuntu 9.

It happens to me every time I create a USB key with reserved extra space, if I create a USB key with settings and documents discarded the error does not occur.

I had the same error. Thanks to Damion in post #4 (https://bugs.launchpad.net/ubuntu/+source/usb-creator/+bug/777957/comments/4) I could create a successful disk after running the command as superuser/root.
