The UMC import module (package ucs-school-umc-csv-import) supports only the legacy CSV format, is hard to maintain and few customers use it. Further development is going into the HTTP-API UMC frontend (package ucs-school-umc-import). 1) Do not install ucs-school-umc-csv-import by default anymore. → Remove from "Recommends" in packages ucs-school-master and ucs-school-singlemaster. 2) Add a hint to section school:setup:umc:csvimport:import of the UCS@school manual how to install it, in case a customers wishes to use it.
We decided to remove this UMC module completely with UCS@school 4.4 *** This bug has been marked as a duplicate of bug 48063 ***
UCS@school 4.4 v1 has been released. https://docs.software-univention.de/release-notes-ucsschool-4.4v1-de.html If this error occurs again, please clone this bug.
