So when you go through this, you don't get the option in step 4 to upgrade?

Running these commands should work
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
I ran into a similar problem before. Also, if your laptop supports booting from USB and you have a flash drive, you can put 13.10 on the stick and upgrade via it.
It's still telling me that no updates are available with the three commands...
