# &app; Manual V&manrevision;

## Introduction

The &app; enables you to install software onto your computer and to manage the software, that is already installed. The software is bundled in so called packages. A single application can even exist of several packages: e.g. the Mozilla Internet Suite is packaged to mozilla-browser, that contains the actual browser, and mozilla-mail , that contains the mail client (this example refers to Debian GNU/Linux and can be different on your distribution).

Nearly all applications reuse the functionality of other applications or libraries (libraries only provide functions to other libraries or applications and are no stand alone applications) to avoid doubled efforts. So the most packages depend on other packages. The &app; resolves the dependencies for you automatically.

Technically the &app; is based on the package manager APT and provides functions, that are similar to the ones of the command line tool `apt-get` in a graphical environment.

In detail &app; provides the following features:

- Install, remove, configure, upgrade and downgrade single and multiple packages.

- Upgrade your whole system.

- Manage package repositories.

- Search packages by name, description and several other attributes.

- Select packages by status, section, name or a custom filter.

- Sort packages by name, status, size or version.

- Browse all available online documentation related to a package.

- Lock packages to the current version.

- Force the installation of a specific package version.

You need root rights to install or remove software packages on your computer.

You can start &app; in the following ways:

Cinnamon menu

- Choose Administration Synaptic Package Manager .

GNOME 3 select Activities

- Choose Show Applications All Synaptic Package Manager .

GNOME 2 Applications menu

- Choose System Tools Synaptic Package Manager .

KDE menu

- Choose Settings Extra Synaptic Package Manager .

Mate Applications menu

- Choose System Tools Synaptic Package Manager .

Command line

- To start &app; from a command line type the following , then press Return:

  `synaptic`

You can render your system unusable.

Synaptic allows you to perform changes on the core of your system.

Always use &app; with care.

### To Upgrade the Whole System

&app; provides two methods for marking packages for upgrade:

Default Upgrade

- The default upgrade method marks upgrades of installed packages only. If the later version of a package depends on not installed packages or conflicts with an already installed package, the upgrade will not be marked.

Smart Upgrade (Dist-Upgrade)

- The smart upgrade method tries to resolve package conflicts intelligently. This includes installing additional required packages and preferring packages with higher priority.

  Smart upgrade is also known as dist-upgrade in the console tool apt-get.

Upgrades to a later operating system major releases have to be performed with the smart upgrade method, e.g. from Conectiva 9 to Conectiva 10 or from Debian Woody to Debian Sarge.

To upgrade your system to the latest version follow these steps:

1. Reload the package information to be aware of the latest versions available:

   - Choose Edit Reload Package Information from the menu.

   - Click on Reload in the toolbar.

   - Press the key combination Ctrl R.

2. Mark all possible upgrades:

   - Click on Mark all Upgrades in the toolbar.

   - Choose Edit Mark all Upgrades from the menu.

3. Choose the upgrade method. Smart upgrade is recommended.

4. Apply the marked changes to actually upgrade the package(s):

   - Click on Apply in the toolbar.

   - Choose Edit Apply Marked Changes from the menu.

   - Press the key combination Ctrl P.

5. You are asked for confirmation. Check the summarized changes that will be applied. To continue with the actual upgrade confirm the changes click on Apply.

6. During the processing of the changes you will see a progressbar. Wait until the changes have been applied. This can take some time depending on the number of changes. Afterwards you will be returned to the main window.

   The progressbar is not available on Debian system. Instead you will see a detailed terminal output.

## Repositories

Packages are made available through so called repositories. The repository contains the packages and an index which includes some basic information about the packages, e.g. required dependencies or a short description.

Repositories can be located on many medias: CD-Rom/DVD, local hard disk, the Web (http,ftp) or remote file system (nfs).

### To Reload the Package Information

To collect the list of all available packages from the repositories choose one of the following methods:

- Choose Edit Reload Package Information from the menu.

- Click on Reload in the toolbar.

### To Edit, Add or Remove Repositories

You can edit, add or delete repositories in the repository preferences.

Open the repository editor with Settings Repositories from the menu.

#### Repository Preferences

Shows the repository preferences

### To Add Repositories From CD-ROM

Choose Edit Add CD... from the menu.

### The Syntax of the APT line

The package manager stores all available repositories in a text based configuration file. Each line describes the type, location and content of one repository.

### Syntax of an APT line e.g. deb http://ftp.debian.org sarge main

Element | Description
deb | The first elements describes the type of the repository. Possible values are deb (Debian binary packages), deb-src (Debian source packages), rpm (RPM binary packages), rpm-src (Redhat source packages), rpmdir (folder that contains RPM binary packages) and rpmdir-src (folder that contains RPM source packages).
http://ftp.debian.org | The second element is the location of the repository. The repository can be accessed by the protocols HTTP and FTP, or locally on a CD, DVD or hard disk.
sarge | The third element describes the distribution for which the packages are made for, see the Debian Developer's Reference for more details on distributions of Debian.
main | The forth element describes sections of the repository that should be included. By default official Debian repositories are separated into the sections main, contrib and non-free, see the Debian Developer's Reference for more details on sections of Debian.

The distribution and section element are not required for each type.

## Custom Filters

Filters enable you to narrow down the list of shown packages by a variety of package attributes.

&app; comes with a set of predefined filters.

## Predefined Filters

Filter | Description
All packages | Display all known packages.
Marked Changes | Display all packages that are marked for a status change.
Pkg with Debconf | Display all packages that can be configured through debconf (Debian only).
Broken | Display only packages with broken dependencies.
Upgradable (upstream) | Display all packages that can be upgraded to a later upstream version.

Because of some interface changes the set of predefined filters changed, too. The old and deprecated filters are not removed automatically by Synaptic.

## Deprecated Filters

Filter | Description
Install | Display only currently installed packages.
Not installed | Display only currently not installed packages.
Upgradable | Display only packages with a later version available.
Broken | Display only packages with broken dependencies.
Programmed Changes | Display only packages marked to be modified.
New in archive | Display only new packages since the last repository update.
Residual | Display only former installed packages that left data or configuration files on the system.
Pkg with Debconf | Display only packages that can be configured through the debian package configuration system, so called debconf.
Obsolete or locally installed | Display only packages that are not (for longer) included in one of the specified repositories.
Search Filter | Display the results of the last package search.

### To Apply Filters

To apply a filter follow these steps:

1. Choose Custom Filters from the category combobox in the main window.

2. Choose the wished filter from the synaptic-win-selector.

### To Edit or Create Custom Filters

Filters can be created, deleted and modified in the filter editor:

Choose Settings Filters from the menu.

#### Edit Filters

Shows the filter editor.

The filter editor contains the following components:

List of Filter

- Shows a list of available filters.

Rules

- Rules allow you to define which packages should be shown in the list. A package has to fulfill all selected criteria.

  Status

- Allows you to search packages by status.

Section

- Allows you to search packages by section.

Properties

- Allows you to search packages by a variety of attributes e.g. name, dependencies or origin.

Keywords

- Keywords are based on debtags. Only Debian GNU/Linux with installed "debtags" supports this feature.

## Known Bugs and Limitations

## Known issues and workarounds

Problem | Workaround
Unsupported locale | Use a locale supported by Xlib.
A failed installation blocks further operations in synaptic | Under some rare circumstances the actual installation or removal of a package can fail. As a consequence all other marked changes are canceled, too. &app; requires a clear environment with no half installed packages to perform additional changes. But at the moment there is no way to continue canceled installations within &app;. To fix this situation type the following command in a terminal, then press Return: `apt-get install -f`
