openSUSE offers a continuous stream of software security updates for your product. By default openSUSE Updater is used to keep your system up-to-date. Refer to Section “Keeping the System Up-to-date” (Chapter 3, Installing or Removing Software, ↑Start-Up) for further information on openSUSE Updater. This chapter covers alternative graphical tools and command line utilities for updating software packages.
The current patches for openSUSE® are available from an update software repository. If you have registered your product during the installation, an update repository is already configured. If you have not registered openSUSE, you can do so by running
+ in YaST. Alternatively, you can manually add an update repository from a source you trust with each update tool. Please refer to the respective application described below for instructions.
