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 3.7, Keeping the System Up-to-date,
(↑ 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.
openSUSE provides updates with different relevance levels. Security updates fix severe security hazards and should definitely be installed. Recommended updates fix issues that could compromise your computer, whereas Optional updates fix non-security relevant issues or provide enhancements.
