Repositories will usually be loaded from the internet, so the URI will be of the form http:// or ftp:// but you can use a Ubuntu CD (do Edit -> Add CD ROM...), or a mounted ISO image file (use a URI of the form file:///media/cdmount/). |

The Synaptic Package manager
There are several ways to install and remove programs on Ubuntu Linux. One of the most used is Synaptic, a graphical manager; others are command line interfaces, like apt-get and aptitude. This document describes how to use the powerful yet easy-to-use Synaptic Package Manager.
These instructions assume that you have permission to run sudo. (If you installed Ubuntu yourself, you do.)
Start Synaptic by selecting: Computer -> System Configuration -> Synaptic Package Manager

How to add or remove a repository with synaptic
In Synaptic, bring up the repositories window: Settings -> Repositories
attachment:PicSynapticPackageManager2.png
Depending on what you want to do you will have to add repositories.
A short explanation of what you see in the window:
- Every line has a tick-box to enable or disable an item, for example the cdrom is disabled, it is also greyed-out to make this more clear.
Next is Type, either deb or deb-src. Packages can either be installed as binary packages, ready to use straight away, or as source packages. Source packages will need to be build first. People use this because they have special requirements.
The third item reads Uri. This is the adress from where you'll be downloading your packages.
To edit a line, select it and you will be able to edit its settings in the second half of the window.
The most common task in the repository-window is enabling universe. You do this by adding universe to your main URI-line. Your settings will then look like in the picture.
Repositories will usually be loaded from the internet, so the URI will be of the form http:// or ftp:// but you can use a Ubuntu CD (do Edit -> Add CD ROM...), or a mounted ISO image file (use a URI of the form file:///media/cdmount/).
Adding and removing programs
Installing or removing programs is a very straight-forward task. You either find the program of choice in the right-upper part of the synaptic-window or you use the *search*-button to find it. Select it by marking the tick-box and press *Apply*. Synaptic might ask you whether it is ok to install additional packages to satisfy dependencies (they just belong together), say *Yes*. Or it will just install them straight away.
How to keep your system up-to-date
Updating your system requires several simple steps. The first one is pressing Reload, this will download the latest package-list from the download-sites.
You can check for upgradable packages now by choosing "Status" from the menu on the left pane. If there are upgradable packages available you will see a entry "Installed (upgradable)". Now you can choose what upgrades to install manually. Alternativly you can you can click on "Mark all upgrades". This will pop up a dialog that asks about the type of upgrade you want to perform. If unsure choose "Default upgrade".
Next you hit "Apply" in the main toolbar. This will open a dialog that descibes the changes that will be performed. Always check those changes before you hit "Apply" in this dialog!

Typed my password upon prompting when i clicked on the "Administrator mode" but was not able to configure it. I installed Kubuntu myself. Any idea why?
I would also hope that there will be a HOW-TO on installing & configuring WPA from Synaptic soon. Thanks!
