Which setup have you tried? As mentioned I have a full disk encryption but changed the partition layout to the following:
ACTIVE '/dev/vg-laptop/root' [176,95 GiB] inherit ACTIVE '/dev/vg-laptop/BACKUP' [51,59 GiB] inherit ACTIVE '/dev/vg-laptop/swap' [4,10 GiB] inherit so as you can see it is a vg-group with the name "BACKUP" and not everything on "root" as it would be in the "guided" partitioning. df output was: /dev/mapper/vg--laptop-root ext4 177G 142G 32G 82% / /dev/sda1 ext2 228M 33M 184M 15% /boot /dev/mapper/vg--laptop-BACKUP ext4 52G 46G 5,2G 90% /opt/BACKUP So have you tried to setup a full disk encrpytion with a changed disk layout? I think that this is the most possible reason for the failure. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1000927 Title: 12.04 new install or update: if LVM + full encrypted disk grub installation fails!
