https://docs.software-univention.de/ucsschool-id-connector/admin.html#sending-system states "The app is using the CA trust store from the UCS host system. The app is restarting if the certificates are updated by update-ca-certificates,..." This doesnt work because root@server:~# head -1 /etc/ca-certificates/update.d/ucsschool-id-connector #!/usr/bin/sh root@server:~# ls -l /usr/bin/sh ls: Zugriff auf '/usr/bin/sh' nicht möglich: Datei oder Verzeichnis nicht gefunden
This happens only on systems that were updated from 4.4. I only tested on a fresh install :( (Keyword usrmerge https://wiki.debian.org/UsrMerge for some reason I thought we had done this) We should use `/usr/bin/env sh` which is available on both 5.0 and 4.4.
