With the UCS@school errata update from 2019-09-11, we published a fix for Bug #49311 that changed the internal behavior of the SchoolComputer.lookup() method.
This introduced a regression in the script /usr/share/ucs-school-import/scripts/migrate_ucsschool_roles which caused it to skip certain computer objects during migration. This can cause tracebacks in parts of UCS@school that rely on the ucsschoolRole attribute to be present in SchoolComputers:

Affected are all systems that upgraded from an UCS@school version <=4.4v1 to >=4.4v1 in the time between 2019-09-11 and 2019-11-27.
The update for Bug #50349 that was released on 2019-11-27 fixes the regression. If you are affected please run the migration script again. You can use the following command to run the migration for the computers of all schools:
$ /usr/share/ucs-school-import/scripts/migrate_ucsschool_roles --computers-school --modify
