Welcome to Ask Ubuntu. Why do you think the package "fpc" should exist? Also, please give us the complete command you issued. Please add the information to your question by editing it. – MadMike Jan 20 '14 at 10:56

To install fpc you should have the Universe repository enabled. From command line, you can do this and then install the application as shown below:

sudo add-apt-repository "deb $(lsb_release -sc) universe"
sudo apt-get update
sudo apt-get install fpc
sudo apt-get install fpc-2.4.4

Source How do I enable the “Universe” repository from the command line?

Synaptic Package Manager is a good graphical package manager, if you might want to give it a try!
