Alternatively, group by package groups. The package groups feature offers a more de-
tailed view of the software grouped by categories. Packages often depend on other
packages; if you select a package, you might be requested to install additional packages
to resolve possible package dependencies.
Grouping by languages is similar to grouping by package groups. Using the languages
view enables you to select packages like translated program messages, documentation,
or special fonts which are needed to support a specific language.
For installing corresponding source packages, use zypper. For more information, see
Section "Installing and Removing Software with Zypper" (Chapter 5, Managing Software
with Command Line Tools, ↑Administration Guide).
6.3.2 Checking Software Dependencies
The software of one package might only work properly if the required package is also
installed. If packages with identical or similar functionality use the same system resource,
they should not be installed at the same time, because this would cause a package con-
flict.
When the package manager starts, it examines the system and displays the installed
packages. When you select a packag to install and remove it, the package manager au-
tomatically checks the dependencies and selects any other required packages (resolution
of dependencies). If you select or deselect conflicting packages, the package manager
indicates this and suggests possible solutions to this problem (resolution of conflicts).
For example, sendmail and postfix should not be installed concurrently.
"Conflict Management of the Package Manager"
prompting you to make a decision. postfix is already installed. Accordingly, you
can decide wheter to install sendmail or remove postfix.
