ZYpp (or libzypp; "Zen / YaST Packages Patches Patterns Products") is a package manager engine that powers Linux applications like YaST, Zypper and the implementation of PackageKit for openSUSE and SUSE Linux Enterprise. Unlike some more basic package managers, it provides a satisfiability solver to compute package dependencies. It is a free and open-source software project sponsored by Novell and licensed under the terms of the GNU General Public License v2 or later. ZYpp is implemented mostly in the programming language C++.

Pleospora betae is a plant pathogen infecting beet. It contains the chemical substances betaenone A, B and [[betaenone C|C]. Pleospora betae develops on dead beet residues and is a marsupial stage of the Phoma betae anamorph, parasitizing on beets and causing a number of harmful diseases.

ZYpp is implemented mostly in the programming language C++. Zypper is the native command-line interface of the ZYpp package manager to install, remove, update and query software packages of local or remote (networked) media. Its graphical equivalent is the YaST package manager module. It has been used in openSUSE since version 10.2 beta1. In openSUSE 11.1, Zypper reached version 1.0. On June 2, 2009, Ark Linux announced that it has completed its review of dependency solvers and has chosen ZYpp and its tools to replace the aging APT-RPM, as the first distribution to do so. Zypper is also part of the mobile Linux distributions MeeGo, Sailfish OS, and Tizen.
