Public bug reported: For unclear reasons (18.04 didn't have this issue), Ubiquity on 20.04 interferes with existing ZFS pools, making them "disappear" (it's not clear what exactly happens).
To repeat (assumes a `/dev/sda` disk): - start a 20.04 Ubuntu Desktop live media - open a terminal - create a zfs pool: `zpool create test /dev/sda` - verify that it's been created: `zpool list` - launch ubiquity: `ubiquity` - open a separate terminal - list the ZFS pools: `zpool list` no pools are now listed.
