You will until you fix the following issue...

^^^ this I believe is the issue. You have a reference to a debian repository 
on an Ubuntu system. This cannot be good. 

Remove is like this:-

Applications --> Accessories --> terminal

sudo gedit /etc/apt/sources.list

comment out (or remove) the lines referencing "debian.org" by either 
deleting them completely or putting a "#" character at the start of those 
line(s).

Then save the file, exit the editor and run the following command again:-

sudo apt-get update

Then try to do the update via the graphical tool.

A word of warning, it's possible that packages have in the past come into 
your system from that debian repository. It is _possible_ this may cause 
conflicts with other installed, or yet to be installed, ubuntu packages.

Lets see what happens after we do the above though eh before we panic :)

Cheers,
Al.
