Through Kolab Systems and/or community support channels, you may be asked to test an update distributed through the updates-testing repository to see if it fixes a bug you have reported. You would then, typically, temporarily enable the updates-testing repository by supplying the <literal>--enablerepo=kolab-2.4-updates-testing</literal> command-line option to YUM, overriding the system configuration file setting.

-                        Since any given package may, at any time, be or become available to the system through both the Kolab repositories as well as through the regular distribution repositories, to avoid the risk of switching back and forth between the two different versions continuously, by mistake or by accident, we recommend you use the following procedure including employing YUM repository priorities to eliminate the risk of running in such problems in the future.

The default repository priority is <code>99</code>. This will set the correct priorities, unless you have repositories configured other than the base operating system repositories (not including 'addons' and 'extras' on CentOS platforms), EPEL and the Kolab Groupware repositories. Should the system happen to already make use of YUM priorities, please make sure the Kolab repositories have the appropriate priority.

This repository is called <emphasis>updates-testing</emphasis>, and is not enabled by default. Through Kolab Systems and/or community support channels, you may be asked to test an update distributed through the updates-testing repository to see if it fixes a bug you have reported. You would then, typically, temporarily enable the updates-testing repository by supplying the <literal>--enablerepo=kolab-2.4-updates-testing</literal> command-line option to YUM, overriding the system configuration file setting.

Should the system happen to already make use of YUM priorities, please make sure the Kolab repositories have the appropriate priority.
