Unity won't install via usb as a clean install

Thanks for sending this in Laura. Looking at the logs, it's not clear what's going wrong. Given your description this is likely to be a problem in either jockey (which the installer calls if you check the "use third-party software"), or partman, the partitioning backend.

Are you checked the "use third-party software" box? Does the bug still occur if you do not check it? If it does not, what is the result of running `sudo jockey-text -a` in a fresh live CD session?

If the bug does still occur regardless of whether or not that box is checked, can you please run the install manually from the live CD desktop in debug mode. To do this, click "Try Install" from the first installer screen, then open a terminal and type `ubiquity -d`. When the installer hangs, run `apport-collect 703552`.

Thanks!

Evan, didn't tick 3rd party and it still hung! Ticked it and hung! No change

Looks like you've found a bug in parted:

Can you please attach the output of the following:
`sudo parted_devices`
`sudo parted -l`

sudo parted_devices
/dev/sda 7682695056 ATA STEC PATA 8GB
/dev/sda 4007657472 USA DISK 2.0

when I do sudo parted -l I get a core dumped

I just had the same problem and followed the instructions left by Evan in the first comment. Tired to install the current daily natty build three times here from today download. Keep getting the same failure when trying to install from the live USB. Tired both Install Now and Try Ubuntu and install from desktop. I am using zsync to capture the current daily build and will try again in a few days. I signed in as this bug affects me but if needed I will create a new one.
