Description Janek Walkenhorst

2016-06-08 18:12:40 CEST

This affects 3.2 too, and therefore "disables"
 <http://errata.software-univention.de/ucs/3.2/428.html>

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


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
