Description Janek Walkenhorst univentionstaff 2016-06-08 18:15:00 CEST
This affects 3.2 too, and therefore "disables" Bug #41364

+++ This bug was initially created as a clone of Bug #40660 +++

When updating from UCS 3.2 to UCS 4.0 the previously used UCRV grub/boot is not migrated to the new mechanism of debconf grub-pc/install_devices.

It was:

# ucr get grub/boot
# debconf-show grub-pc

But it should be (example):

# debconf-show grub-pc
* grub-pc/install_devices: /dev/vda

During the update grub was never installed:
# grep -E '^Installing for' /var/log/univention/updater.log
