osprober prints errors about ZFS partitions

[BertN45]

It is probably a minor problem. I did run an upgrade of my official ZFS installation in a VM.
It did produce an error:

device-mapper: reload ioctl on osprober-linux-sdb6 failed: Device or resource busy
Command failed.

I have a dual boot so afterwards I did boot from ext4 and did run update-grub and that did report the same error.

See attachment, first lines the update-grub and the lines afterwards the last part of the zfs apt upgrade.

I could boot the systems afterwards and Linux 5.3.0-17 were loaded.

osprober complaining about ZFS is a known issue. I don’t know if I bothered to file a bug report, so this will probably be the report for that.

Side question: where did you find an installer image with ZFS support? I tried the daily yesterday but I had no ZFS option.

I did find it on Tuesday 14:30 local time, 19:30 GMT on the "Ubuntu
daily builds pending" as far as I can reconstruct it. I also downloaded
Ubuntu Mate that day and the first dirty install worked, but when I
tried to install the same ISO again, it showed the known bug.

Status changed to 'Confirmed' because the bug affects multiple users.
