You need to dress the line 54 of the file /etc/apt/
Open a Terminal from the menu Applications → Accessories → Terminal and type:
(if the system ask you a password give your user password, you will not see nothing when you type it, then press enter)
sudo gedit /etc/apt/
Tip: to view the line numbers: in the just opened "gedit" file editor please Edit → Preferences → [view] activate the line numbers
Save and exit then retry to update the system.
If you are still in trouble please copy and paste the entire file contents here.

So what you are saying is the CD's from England are unsupported or a restricted
version. What if I reinstall this version and update after I get the Update
Manager working again, would that work?
