install.py crashed with TypeError in main()

Confirming, I get exactly the same crash. Problem is quite obvious:

   'bs=%sM'

this needs a "% somenumber" appended, or a hardcoded block size (which probably isn't unreasonable).

Although the "bs=%sM" is wrong and will certainly confuse dd, it's not the source of this particular crash. It is

  'count=1' % persist

I think this line would make most sense:

  popen(['dd', 'if=/dev/zero', 'bs=%s' % persist, 'of=%s/casper-rw' % target, 'count=1'])

Confirmed that this lets the installation finish.

Works wonderfully now, USB stick boots fine.

usb creator was installing on a 8gb stick when fatal error occured.

I was installing Alpha 6 on a 2gb stick when crash...

Same crash while trying to install Jaunty Alpha 6 i386 to a 8 GB USB stick.

I don't know whether this matters, but: the crash occured 1 second after clicking the network manager.

@Martin Pitt:

Is your patch (right?) included in Jaunty Alpha 6? Below you can see what my Jaunty Alpha 6 has, so it's looks patched, but I still got the crash.

FWIW:

Using usb-creator from Linux Mint 6 (based on Ubuntu 8.10), I was able to write the Jaunty-Alpha6-iso to a USB stick. I guess that means the bug was introduced between 8.10 and 9.04.

This problem present my clean installed Jaunty Alpha6 system.
How can I test Martin Pitt fix?

I doed Martin Pitt modification with /usr/share/usb-creator/install.py
with the 134. line.
Attached the patch. Usb-creator nice doed the 64 bit jaunty usb stick
with following command:
usb-creator -i ~/jaunty-desktop-amd64.iso
I use full remaining space with storage.

Anybody see with following link:

As of today's updates to a bunch of packages including the USB creator I was able to install onto a USB. The USB did then boot and run.

However I wasn't able to do an install from the USB because the partition frame didn't have any partitions in it?? I get the same thing trying to install from CD unless I use alternate CD, which works. It's a Compaq Presario 3.3 gHz Celeron.

When I tried to shut down the USB, there was an error; could have been flash error, I don't know.

Partial success, anyway.
