The file wont update It tells me to mount the cdrom using apt-cdrom I do that and then it tells me to do that to the cd set? does anybody have this problem on there netbook? If you need more info i will get it thank you.

Use the Synaptic Package Manager to remove the CD-ROM as a repository.

On the Gnome Desktop upper bar click the following:

System -> Administration -> Synaptic Package Manager

Enter your password.

When the Synaptic Package Manager window opens click the following:

Settings -> Repositories

When that window opens it will be on the Repositories tab. Near the bottom you will see CD-ROM. Uncheck that entry. Then click on the Close button.

Close the Synaptic Package Manager.

The Update Manager should now look to the Internet for all of its updates.
