Quick Start Guide

once for static repositories such as CDs or DVDs, whereas repositories whose
content changes often should be refreshed frequently. The easiest way to keep
a repository's cache up-to-date is to choose Automatically Refresh. To do a
manual refresh click Refresh and select one of the options.
Keep Downloaded Packages
Packages from remote repositories are downloaded before being installed. By
default, they are deleted upon a successful installation. Activating Keep Down-
loaded Packages prevents the deletion of downloaded packages. The download
location is congured in /etc/zypp/zypp.conf, by default it is /var/cache/zypp/
packages.
Priority
The Priority of a repository is a value between 1 and 200, with 1 being the highest
priority and 200 the lowest priority. Any new repositories that are added with YaST
get a priority of 99 by default. If you do not care about a priority value for a certain
repository, you can also set the value to 0 to apply the default priority to that
repository (99). If a package is available in more than one repository, then the
repository with the highest priority takes precedence. This is useful if you want
to avoid downloading packages unnecessarily from the Internet by giving a local
repository (for example, a DVD) a higher priority.
IMPORTANT: Priority vs. Version
The repository with the highest priority takes precedence in any case. There-
fore, make sure that the update repository always has the highest priority (20
by default), otherwise you might install an outdated version that will not be
updated until the next online update.
If you add repositories providing new versions for programs shipped with
openSUSE (for example a repository with the latest KDE or GNOME version),
make sure they have a higher priority than the standard repositories, otherwise
packages from these repositories will not be installed by default.
Name and URL
To change a repository name or its URL, select it from the list with a single-click
and then click Edit.
5.4.3 Managing Repository Keys
To ensure their integrity, software repositories can be signed with the GPG Key of
the repository maintainer. Whenever you add a new repository, YaST oers to import
its key. Verify it as you would do with any other GPG key and make sure it does not
change. If you detect a key change, something might be wrong with the repository.
Disable the repository as an installation source until you know the cause of the key
change.
