UCS@school-Update

1. UCS@school-Update#

This document contains the changelogs with the detailed change information for the update of UCS@school from version 5.2v5 to 5.2v6.

The change information for previous version jumps can be found at the changelog overview page.

1.1. Maintenance release 5.2v6#

UCS@school 5.2v6 is a maintenance release with bug fixes.

What’s new?

  • The ucsschool_purge_timestamp.py hook has been updated to use the new map/unmap functions on UCS systems running version 5.2-6 and above. This fixes UMC issues in combination with delegated administration.

  • Teachers can now reset passwords regardless of whether the student’s account is locked.

  • Join failures into domains that previously took part in an AD takeover are now fixed.

1.1.1. Activating the updated purge timestamp hook early#

Note

UCS 5.2-5 Errata 416 is required on all systems in the domain to activate the hook early.

The updated ucsschool_purge_timestamp.py hook is automatically activated during the update to UCS 5.2-6. To activate it on UCS 5.2-5 systems with the required errata applied, run the following commands:

$ udm settings/udm_hook modify \
    --set ucsversionend=5.2-4 \
    --dn "cn=ucsschool_purge_timestamp_525,cn=udm_hook,cn=univention,$(ucr get ldap/base)"
$ udm settings/udm_hook modify \
    --set ucsversionstart=5.2-5 \
    --dn "cn=ucsschool_purge_timestamp,cn=udm_hook,cn=univention,$(ucr get ldap/base)"

1.2. General notes on the update#

During the update, services within the domain may fail. For this reason, the update should be performed within a maintenance window. It is generally recommended to install and test the update in a test environment first. The test environment should be identical to the production environment.

Please note that depending on the size of the UCS@school environment, this update may take longer than usual to complete.

1.3. Update process#

Major updates for UCS@school are released in the Univention App Center as a standalone app update. Minor updates and bug fixes (errata for UCS@school) that do not require interaction with the administrator are released in the repository of the already released app version of UCS@school. The changelog documents that Univention issues with each UCS@school app version are then expanded accordingly with a new section that shows which packages were released at what time and which errors were fixed in the process.
