I have since updated to Ubuntu 10.10 and I am no longer experiencing any problems with update. I have also replaced one of my hard drives as I noticed some irregularities that suggested that the disk was about to die. If no one else is experiencing this I would suggest that my faulty hard drive was the source and close this bug report.
