Operation Manual

• 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 Package > All

Packages > Update if Newer Version Available from the main menu.

All repositories are checked for possible update candidates, using the following

policy: YaST rst 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:

1. Repository priority: Prefer the package from the repository with the highest

priority.

2. 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; otherwise: x86_64 > i686 > i586).

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.

NOTE: Update Unconditionally

If you choose Package > All Packages > Update Unconditionally instead,

basically the same criteria apply but candidate package found is installed

unconditionally. Thus, choosing this option might actually lead to down-

grading some packages.

To make sure that the packages for a mass update derive from a certain repository:
