Installing applications in Linux (part II) E-mail

To illustrate this, I am going to use two real world examples. These are applications that I use myself: Ubuntu Tweak and Gantt Project.
 
The first one is Ubuntu Tweak. This is a great little utility, similar to Microsoft's TweakUI PowerToy, in that Ubuntu Tweak brings together all the Graphical User Interface (GUI) tweaks that you'd have to hunt around in various other screens to find. The author is also constantly updating it with bigger and better features, so it needs to be updated every now and again.
 
Ubuntu Tweak isn't available through the default Ubuntu repositories. I can't find it and easily install it using Add/Remove Applications or Synaptic. So, how do I install it?
 
Firstly, you download the file (this is a .deb file, which means that it is Debian compatible. Debian is the base Linux distribution upon which Ubuntu is built) from the website. Once downloaded, double-click on the file to install it. A window will open up with some details about the file itself - description, version, author's contact details, etc. Here you can check that you have downloaded the correct file and version.

Look to see that all the "dependancies" are satisfied. "Dependancies" are programs which are required to be there to make this one work. Think of it like driving a car - a "dependancy" would be the presence of fuel in the tank to make it work.

Click on "Install Package" and put in your password. Sit back for a few seconds and watch it install. Once installed, it will tell you that the installation was finished. Click Close and then close the package install manager. Ubuntu Tweak is available from the Applications menu (like the Windows Start menu) under System Tools.

It really is that easy and not at all scary!
