Public bug reported:
I have tried installing Kubuntu 15.04 on my laptop containing 4 SSDs
which I want to combine using raid 0.
I performed the following steps:
- boot from USB
- choose try Kubuntu
- install mdadm
- create raid 0 array
- start installation
- whole disk, guided partitioning
The installation fails with "Executing 'grub-install /dev/sda' failed".
I tried the following without luck:
- dist-upgrade before installation
- using Kubuntu 14.04.02 instead of 15.04
- manual partitioning
- using LVM w or w/o encryption
- pre-creating swap/ext4 partitions vs. partitioning during installation
