This doesn't appear to be a problem with "twisted (Ubuntu)". More likely it is a hardware failure - either hard drive, memory, or network card. Some part of the installation tool chain should probably be checking a checksum of some sort (although if you have bad memory, your data might pass a checksum check and *then* be corrupted causing a problem like this).
