Packages in Debian are kept in repositories. These repositores are listed in you /etc/apt/sources.list file. You can edit them by editing that file with a text editor or you can edit them inside synaptic. To do so open the list of repositories by clicking with your mouse inside synaptic:
Settings -> Repositories
This will open up a list of repositories. The list will show whether a repository is enabled or not, and what type of repository it is. "deb" repositories are the binary files for packages and "deb-src" are the source files. Add and delete the repositores you want. Type the web address in the URI slot, what distobution type in the distribution slot, and which sections of the repository I want to access in the Section slot. For example if I knew the binaries packages I wanted for the "stable" distribution was located at http://mirrors.xmission.com/debian/ in the main contrib and non-free sections I would type:
URI: http://mirrors.xmission.com/debian/ Disribution: stable Section(s): main contrib non-free
I would then click "OK" at the bottom of the screen.
To add a new repositories click on the "new" button. To delete a repository click on the "delete" button. To edit a repository click on the repository in the list.
New packages and updates are being added and removed from repositories often. Your system needs to be up-to-date. To do so click on the reload button at the top left hand corner of the screen. Synaptic wil then download new package information. Some times synaptic "hiccups" and gives an error. More often then not you just have to update again to fix the error.
Once you have preformed this successfully with no errors your package list is up to date.
Once you have updated your system there will often be packages that need to be upgraded. Click on the "Mark All Upgrades" button. A screen will pop up showing packages that need to be upgraded, click "OK" . Click on the "Apply" button at the top of the screen. This will bring up a screen to prompt you if you wish to apply the changes. Review the list makeing sure these are changes you are comfortable with. Then click "OK" Synaptic will begin upgradeing your packages. Note: it is sometimes helpful to click on the terminal button while Synaptic is upgrading your packages so that you can see what is going on and answer any questions the terminal sometimes asks you.
