Irihapeti,

Ouch, I thought we had this nailed. Can you put 'set -x' in the places I mentioned in comment #36 (https://bugs.edge.launchpad.net/ubuntu/+source/ubiquity/+bug/536673/comments/36), run ubiquity in debug mode (alt-f2 `ubiquity -d` after pressing "Try Ubuntu"), and then do an alt-f2, `apport-collect 536673`.

Also, when the installer says it cannot unmount a device, can you open a terminal and type mount to first figure out where it's mounted, then `sudo lsof /wherever/the/mountpoint/is`. This will let us know what programs are blocking migration-assistant from unmounting that device. Please attach the output of that command to this bug.

Thanks again for all of your help!
