Problem upgrading to Ubuntu 8.10

[JOCAAN]

Hi,
I've just upgraded to Ubuntu 8.10 from 8.04 version and I'm unable to boot it.
After restarting my pc after upgrading Ubuntu seems to work but it stops loading in "running local boot scripts (/etc/rc.local)". A friend have told me to type apt-get update in terminal but when I do this I see lots of messages "failed to fetch ..." and nothing happens.
I'm a noob in Linux. Remember I can't acces to the Gnome desktop I only can use terminal.

How did you upgrade? Execute this

sudo apt-get clean all
sudo apt-get update
sudo apt-get dist-upgrade

Post a few error messages here, if any.

I upgrade from Ubuntu 8.04 using update manager.
When I try your code I get some errors after typing sudo apt-get update
There appear some messages like "Failed to fetch http://security.ubuntu.com/ubuntu/di...ty/Release.gpg Could not resolve 'security.ubunu.com' " All these messages end with the following sentence: "Some index files failed to download, they have ben ignored or old ones instead".
Finally there is a message telling me "You may want to run apt-get update to correct these problems".
My Internet connections works properly (is the one I'm using to post here).

Thanks for your answer

Post the contents of /etc/apt/sources.list file here.

But how to get these contents using terminal?

Isn't Graphics working in your machine?

cat /etc/apt/sources.list

No they aren't (i am unable to load Ubuntu) but I've got the contents of /etc/apt/sources.list using an Ubuntu live cd.

Post the contents of /etc/apt/sources.list file here.
