9.04 to 9.10 upgrade not working

[imperative]

I am having problems using the automated "upgrade" tool through the update manager, but I just today updated otherwise with it. It appears that it has something to do with a source? Sorry, I'm fairly new to ubuntu. Any help would be greatly appreciated!
Thanks,
Imperative.

What is the output of:

cat /etc/apt/sources.list
?

Thanks for responding,
I just copied the seemingly relevant piece of the output:

deb-src http://archive.canonical.com/ubuntu jaunty partner

Edit it with

gksudo gedit /etc/apt/sources.list
See the line

deb-src http://security.ubuntu.com/ubuntu jaunty-security multiverse\
Remove the backslash at the end of the line so it reads

deb-src http://security.ubuntu.com/ubuntu jaunty-security multiverse
Save and exit. Does that fix it?

Thanks much! It seems that everything is working wonderfully now. The new packages are downloading.
