ok run:

gksudo gedit /etc/apt/sources.list

add a hash character (a '#') to the start of the lines with the word 'archive' in, save the new file and close gedit, then run:

sudo apt-get update

Then attempt the upgrade

Dear Actionparsnip

I have exactly done as you told me but the result remains the same, I can still not upgrade, as a statement to ask you if my action was correct, here is the way I have added the #archive to the gedit :

#archive# deb cdrom:[Ubuntu 10.10 _Maverick Meerkat_ - Release i386 (20101007)]/ maverick main restricted
