I managed to solve the problem in a manner that doesn't seem to correspond with the automated response. I ran the installation to system disk /dev/sdd rather than /dev/sda. However grub was installed to /dev/sda and that failed (not the download of updates as I wrote earlier). I had several failed attempts with the same system drive and also tried another system drive (both of the SSDs) and that also failed for grup. Then I unplugged all the other drives and kept just the system drive during installation. This worked perfectly and grub installed without any problem. This leads me to believe there is a weak spot in the grub installation scripts.
