** Description changed:

  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".
+ 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
