Its looking for the CD ROM.

Open "Update Manager"

Then click "Settings" and select the "Ubuntu Software" tab. At the bottom of the page one or more CDs may be listed.

Make sure they are all unchecked and try to update again.

Either that or back-up and do a Clean install. This would my preference as a lot has changed between 11.10 and 12.04 or 12.10 but you can upgrade either way

Or run:

gksudo gedit /etc/apt/sources.list

Comment out the top few lines which reference the CD. Save the new file. Then run :

sudo apt-get update

It should now be smoother

Please read this:

https://wiki.ubuntu.com/Releases

Ubuntu 11.10 will be end-of-life and not supported anymore starting May 9, 2013.

I suggest performing a clean install of Ubuntu 12.04 LTS which is supported until April 2017.
