Now it's time to check for updates and install them. This is done using the Update Manager. If you see a notification in the taskbar that new updates are available, you can start the Update Manager by clicking on the update icon; otherwise you can start the Update Manager by going to System > Administration > Update Manager:
If new updates are available, the Update Manager will tell you so (you can click on the Check button to refresh the list), and you can click on the Install Updates button to install them. In my case, no updates were available:
4 Inventory Of What We Have So Far
Now let's browse all menus to see which of our needed applications are already installed:
You should find the following situation ([x] marks an application that is already installed, where [ ] is an application that is missing):
Other: [ ] VMware Server
[ ] TrueType fonts
[ ] Java
[x] Read/Write support for NTFS partitions
So some applications are already on the system. NTFS read-/write support is enabled by default on Debian Lenny.
5 Configure Additional Repositories
Some packages like the Adobe Reader are not available in the standard Debian repositories. The easiest way to make such packages available to your system is to add the Debian-Multimedia repository.
First we open a terminal (Applications > Accessories > Terminal):
... and edit /etc/apt/sources.list:
Add contrib and non-free to the official Lenny repositories that are already in the file, e.g. as follows...
deb http://ftp2.de.debian.org/debian/ lenny main contrib non-free
deb-src http://ftp2.de.debian.org/debian/ lenny main contrib non-free
deb http://security.debian.org/ lenny/updates main contrib non-free
deb-src http://security.debian.org/ lenny/updates main contrib non-free
... and add the Debian-Multimedia repository (you can find a mirror close to you here), e.g. like this:
deb http://ftp-stud.hs-esslingen.de/pub/Mirrors/debian-multimedia/ stable main
deb-src http://ftp-stud.hs-esslingen.de/pub/Mirrors/debian-multimedia/ stable main
Then download the debian-multimedia-keyring package and install it:
