I try to install programs with apt-get install but always it shows same error: unable to locate package. For example I try to install the language-support-fonts-fa ; here's what happens:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package language-support-fonts-fa

Well, this is normal as long as language-support-fonts-fa is not in your current repositories.

To check if a package is in the repositories, use the following command:

apt-cache search <package_name>

In this case, you can download and install manually language-support-fonts-fa package from here: http://packages.ubuntu.com/lucid/all/language-support-fonts-fa/download

Well, for your example it's likely that you're missing the PPA you need to install that package. The best way to add a PPA is to follow the instructions here. But to summarize, you would do something like this:

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:ubuntu-langpack

Now, at this point you need to refresh the package indexes on your machine:

sudo apt-get update

After this you should be able to add the package you want.

This is a bit different than the other answer in that package dependencies will be installed and that future package updates will be noticed and installed each time you do a sudo apt-get update && sudo apt-get dist-upgrade.
