I can't to write arabic letter, and other problem I can't download flash player

You can install the flash player by entering the following command in your terminal:
sudo apt-get install flashplugin-nonfree

[Now it will ask you to enter the root password , once you entered the password it gives you option [Y/n]. Press Enter or Type Y and Enter it will download the flash player and installs in your machine]

Restart the browser.

"for your answer the me terminal doesn't work i.e when i write command it say me this command doesn't existance ."

You can also find the Flash player in Software Center without having to type any commands:

1. Open Applications > Ubuntu Software Center
2. Type "flash plugin" into the search field
3. Find Adobe Flash Plugin 10 and install it

This should work at least on latest versions of Ubuntu.

As for commands, when you need help and someone gives you instructions for a command, it's usually best to copy and paste the command into the terminal rather than re-typing it. That way you can avoid typos.

This My Problem:

The repository may no longer be available or could not be contacted because of network problems. If available an older version of the failed index will be used. Otherwise the repository will be ignored. Check your network connection and ensure the repository address in the preferences is correct.

Intrepid version is not supported today, and so repository was canceled.
You need to upgrade to the latest Natty 11.04 version or Long Term Support (LTS) 10.04.3 Lucid.
