Public bug reported: I'm trying a more particular partitioning scheme and every time ubiquity fails to finish the grub install.
I have 2 nvme drives, identical, formatted full disk with btrfs in raid0 to make my rootfs. Additionally, for boot (ext4) and efi partitions, a separate microsd card. Before finishing, ubiquity shouts a failure and looking in I can see that grub failed to install. I managed to do this particular partitioning scheme using Arch Linux, and installing grub as per the wiki worked without any error or warning. I can't understand why there is something opinionated in Ubuntu's installer that would fail grub installation.
