I am currently running Ubuntu 13.04 on a dual boot with Windows 8 on my Lenovo Y500, and when I try to upgrade to 13.10 I get this:

Checking for a new Ubuntu release
authenticate 'saucy.tar.gz' against 'saucy.tar.gz.gpg' 
extracting 'saucy.tar.gz'
Segmentation fault (core dumped)

Does anyone know of any fixes for this issue?
