Open the Software Center, click Edit → Software Source, and deselect the CD at the bottom of the screen.

Or you can edit /etc/apt/sources.list and comment out the top few lines

I opened the Software Sources dialog box from Settings button in Update Manager. At the top of the list under the Other Software tab there were two checked entries:
1) cdrom [Lubuntu 13.04 _Raring Ringtail_ - Release i386 (20130423.1)']/raring main multiverse restricted universe
2) cdrom [Ubuntu 13.04 _Raring Ringtail_ - Release i386 (20130424)']/raring main restricted

 The update completed successfully after I unchecked option 1 ( for Lubuntu).
Thanks
