Ubiquity fails to continue, stuck in loop

[Christopher Crews]

Ubiquity gets stuck in never ending loop when selecting which disk to install to.

Page: Installation Type
- Selected "Erase disk and install Ubuntu"
- Advanced features > ZFS
- Clicked Continue
Page: Erase disk and install Ubuntu
- Select Drive: options [/dev/nvme0n1,/dev/nvme1n1,sda]
  - selected /dev/nvme0n1
- Clicked Install Now

Ubiquity just returns to the "Installation Type" page and doesn't install

I DO NOT get any error message or dialog box saying that something has went wrong, it just loops continuously.

I had this exact same problem with ZFS on 19.10 and filled a bug then as well, here
is the link: https://bugs.launchpad.net/bugs/1851411
which was marked a duplicate of https://bugs.launchpad.net/bugs/1853864 but that bug was fixed, so it's obviously not a duplicate.
