After upgrading from 0.5.8 to 0.5.8build2 this bug started appearing.

Thanks for your report. Confirmed with 0.5.8build2.

Downgrading and pinning to 0.5.8 is the workaround for now.

Hi, just marked my issue as duplicate of this one.
I can confirm the issue, and also, that the issue can also be resolved by downgrading to 0.5.8build1 (https://launchpad.net/ubuntu/impish/amd64/zsys/0.5.8build1).

Installing the package jibel linked also fixed bug 1966818

[Jean-Baptiste Lallement (jibel)]

A pool compatibility property has been added to ZFS 2.1 but not to the go binding.

[Launchpad Janitor (janitor)]

This bug was fixed in the package zsys - 0.5.9

---------------
zsys (0.5.9) jammy; urgency=medium

  [ Gabriel Nagy ]
  [ Jean-Baptiste Lallement ]
  [ Didier Roche ]
  * Take patched libzfs binding compatible with zfs 2.1 (LP: #1967585)
