UCS 2.4 - Univention

11 Software maintenance
The package lists themselves do not prompt the installation or removal or packages. Package lists are
used much more often in package policies relating to specific system roles, which allow the installation or
removal of packages.
Specific package policies are available for the different system roles (see table). This makes it possible to
link the policies with the domain base and apply a single policy to all computers with the same system role
in the domain without any consequences for computers with other system roles. For example, a package
selection in the package policy for managed clients only applies to computer with the managed client
system role. The policies can also be edited on the appropriate tab of the respective computer objects.

The following steps must be performed when using package lists.
New packages list are created under Navigation ➞ univention ➞ packages in Univention Directory
Manager.
Notes on the creation of package list objects can be found in Chapters 4.4 und 4.5.11.
The entry Settings: Package list is selected from the Add new object at current position menu and a
Name for the package list entered in the appropriate text field.
The name of the desired package is entered in the Package List input field. For example, if the Emacs
editor should be installed on all managed clients. The name of the package is entered without the version
number and the ending .deb, which gives emacs. The package is entered with the [Add] button. Further
package names can be entered as required.
The package list is saved by clicking on [Ok]. The package lists created can be used in a package policy
specific to a system role. A policy is then created directly on a computer object.
A computer object is opened on which the packages from the package list should be installed, e.g., on a
managed client. The [Packages] tab is opened (see Figure 11.2). There are two areas in which package
lists can be selected. Packages which should be installed can be given in the upper area and packages
which should be deleted can be given in the lower area. The previously created package list is selected
from the Package list menu. The package names contained in the package list can not be selected after
each other under Package Installation list and added to the list of packages to be installed using the Add
button.
The settings are saved by clicking on [Ok].
A package policy specific to system roles created in this way can also be reused. The path to the policy is
given in the Configuration field on the policy itself. For example, the entry Packages can be selected via
(current) ➞ Policies on a computer object and the previously created policy selected in the Configuration
menu . Once the page has been refreshed, the values are shown in the text field which were entered
originally. These settings apply to all managed clients below the computer container on activation.
