Public bug reported: On a fresh and up-to-date Ubuntu 20.04 amd64 installation I configured two encrypted partitions on the same hdd. On these I created a stripped zpool. After login I can import and mount the pool without problems, but the at-boot import fails after the first partitions is available and never tried again.
