[Bug 1906217] [NEW] ubiquity fails on grub on custom patitioning with boot and efi on separate microsd

[Madalin Ignisca]

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.
