Synaptic allows installation, upgrading and removing of programs. 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 (in Ubuntu 4.10 warty) or System -> Administration -> Synaptic Package Manager (in Ubuntu 5.04 hoary and later)

How to add or remove a repository with synaptic

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

For Hoary Hedgehog and Breezy Badger, the system will keep you informed of any updates. A red circle will appear in the upper right-hand corner by the volume control.

Warty Warthog

To keep your system updated, launch Synaptic. Click on the Reload button, then the Mark all changes button, followed by the Apply button.

You should do this about once a week. If there are no updates, nothing will happen.
