Comment 6 for bug 1864791

repeat of last test (#5)..
  - / (sda9) partition has lubu system (format),
  - re-use sda8 for /home (no-format)

I was unable to 'select' format for sda9 partition, so I changed format to 'reiser' then accepted; then returned it to ext4 & format was selected..

I had the https://bugs.launchpad.net/ubuntu/+source/calamares/+bug/1864787 error again :( so this could be marked 'New' again, as I now believe it's an issue - however it's also likely a duplicate using that same logic.

Command: sfdisk --force --append/sda
Command: mkfs.ext4 -qF /dev/sda9
