Debootstrap Errors on Two Different Install Images

[buzzingrobot]

I'm getting an identical "debootstrap" error at the same point in the install with both the mini.iso and the alternate ISO image (12.04), followed by a cascade of other errors if I tell it to try again.

What's going on?

(Tried a "regular" image. As usual here, it doesn't work. Boots into the purple screen, then a black screen, then the machine locks up. That's due to the kernel bug re: nouveau and my Nvidia card. Again, as usual, can't get to a grub prompt. Can only get to the "boot:" prompt. None of the offered options will boot.)

My mistake. (Imagine that).

I was sizing partitions in megabytes, not gigabytes. Only off by a factor of 1000.
