Use YaST's software management module to search for software components you want to add or remove. YaST resolves all dependencies for you. To install packages not shipped with the installation media, add additional software repositories to your setup and let YaST manage them. Keep your system up-to-date by managing software updates with the update applet.
Change the software collection of your system with the YaST Software Manager. This YaST module is available in two flavors: a graphical variant for X Window and a text-based variant to be used on the command line. The graphical flavor is described here—for details on the text-based YaST, see Book “Reference”, Chapter 1 “YaST in Text Mode”.
When installing, updating or removing packages, any changes in the Software Manager are not applied immediately but only after confirming them with
or respectively. YaST maintains a list with all actions, allowing you to review and modify your changes before applying them to the system.A local or remote directory containing packages, plus additional information about these packages (package metadata).
A short name for a repository (called Alias
within
Zypper and within YaST). It can be
chosen by the user when adding a repository and must be unique.
Each repository provides files describing content of the repository (package names, versions, etc.). These repository description files are downloaded to a local cache that is used by YaST.
Represents a whole product, for example openSUSE® Leap.
A pattern is an installable group of packages dedicated to a certain
purpose. For example, the Laptop
pattern
contains all packages that are needed in a mobile computing environment.
Patterns define package dependencies (such as required or recommended
packages) and come with a preselection of packages marked for
installation. This ensures that the most important packages needed for a
certain purpose are available on your system after installation of the
pattern. However, not necessarily all packages in a pattern are
preselected for installation and you can manually select or deselect
packages within a pattern according to your needs and wishes.
A package is a compressed file in rpm
format that
contains the files for a particular program.
A patch consists of one or more packages and may be applied by means of delta RPMs. It may also introduce dependencies to packages that are not installed yet.
A generic term for product, pattern, package or patch. The most commonly used type of resolvable is a package or a patch.
A delta RPM consists only of the binary diff between two defined versions of a package, and therefore has the smallest download size. Before being installed, the full RPM package is rebuilt on the local machine.
Certain packages are dependent on other packages, such as shared
libraries. In other terms, a package may require
other
packages—if the required packages are not available, the package
cannot be installed. In addition to dependencies (package requirements)
that must be fulfilled, some packages recommend
other
packages. These recommended packages are only installed if they are
actually available, otherwise they are ignored and the package
recommending them is installed nevertheless.

Installing source packages with YaST Software Manager is not possible at
the moment. Use the command line tool zypper
for this
purpose. For more information, see
Book “Reference”, Chapter 2 “Managing Software with Command Line Tools”, Section 2.1.2.5 “Installing or Downloading Source Packages”.
Instead of updating individual packages, you can also update all installed packages or all packages from a certain repository. When mass updating packages, the following aspects are generally considered:
priorities of the repositories that provide the package,
architecture of the package (for example, AMD64/Intel 64),
version number of the package,
package vendor.
Which of the aspects has the highest importance for choosing the update candidates depends on the respective update option you choose.
To update all installed packages to the latest version, choose
› › from the main menu.All repositories are checked for possible update candidates, using the following policy: YaST first tries to restrict the search to packages with the same architecture and vendor like the installed one. If the search is positive, the “best” update candidate from those is selected according to the process below. However, if no comparable package of the same vendor can be found, the search is expanded to all packages with the same architecture. If still no comparable package can be found, all packages are considered and the “best” update candidate is selected according to the following criteria:
Repository priority: Prefer the package from the repository with the highest priority.
If more than one package results from this selection, choose the one with the “best” architecture (best choice: matching the architecture of the installed one).
If the resulting package has a higher version number than the installed one, the installed package will be updated and replaced with the selected update candidate.
This option tries to avoid changes in architecture and vendor for the installed packages, but under certain circumstances, they are tolerated.
If you choose
› › instead, the same criteria apply but any candidate package found is installed unconditionally. Thus, choosing this option might actually lead to downgrading some packages.To make sure that the packages for a mass update derive from a certain repository:
Choose the repository from which to update as described in Section 9.2.1, “Views for Searching Packages or Patterns” .
On the right hand side of the window, click

to start the mass update.Most packages are dependent on other packages. If a package, for example, uses a shared library, it is dependent on the package providing this library. On the other hand some packages cannot coexist with each other, causing a conflict (for example, you can only install one mail transfer agent: sendmail or postfix). When installing or removing software, the Software Manager makes sure no dependencies or conflicts remain unsolved to ensure system integrity.
In case there exists only one solution to resolve a dependency or a conflict, it is resolved automatically. Multiple solutions always cause a conflict which needs to be resolved manually. If solving a conflict involves a vendor or architecture change, it also needs to be solved manually. When clicking
to apply any changes in the Software Manager, you get an overview of all actions triggered by the automatic resolver which you need to confirm.By default, dependencies are automatically checked. A check is performed every time you change a package status (for example, by marking a package for installation or removal). This is generally useful, but can become exhausting when manually resolving a dependency conflict. To disable this function, go to the main menu and deactivate

Packages that are already installed are displayed in a green frame.Unless you are very experienced, follow the suggestions YaST makes when handling package conflicts, otherwise you may not be able to resolve them. Keep in mind that every change you make, potentially triggers other conflicts, so you can easily end up with a steadily increasing number of conflicts. In case this happens,
the Software Manager, all your changes and start again.In addition to the hard dependencies required to run a program (for example a certain library), a package can also have weak dependencies, that add for example extra functionality or translations. These weak dependencies are called package recommendations.
The way package recommendations are handled has slightly changed starting with openSUSE Leap 42.1. Nothing has changed when installing a new package—recommended packages are still installed by default.
Prior to openSUSE Leap 42.1, missing recommendations for already installed
packages were installed automatically. Now these packages will no longer
be installed automatically. To switch to the old default, set
PKGMGR_REEVALUATE_RECOMMENDED="yes"
in
/etc/sysconfig/yast2
. To install all missing
recommendations for already installed packages, start › and choose › .
To disable the installation of recommended packages when installing new
packages, deactivate --no-recommends.
If you want to install third-party software, add additional software repositories to your system. By default, the product repositories such as openSUSE Leap-DVD 42.2 and a matching update repository are automatically configured. Depending on the initially selected product, an additional repository containing translations, dictionaries, etc. might also be configured.
To manage repositories, start YaST and select

A Service in this context is a (RIS) that can offer one or more software repositories. Such a Service can be changed dynamically by its administrator or vendor.Each repository provides files describing content of the repository (package names, versions, etc.).
