Comment 9 for bug 1769937

I still see the failure:

$ sudo zpool create -O canmount=off -O mountpoint=none -R /mnt/rpool-25582 -t rpool-25582 rpool /dev/mapper/loop4p1
cannot create 'rpool': no such pool or dataset

$ dmesg | grep ZFS
[ 8.174263] ZFS: Loaded module v0.7.5-1ubuntu16.3, ZFS pool version 5000, ZFS filesystem version 5

The running zfs kernel module is version "v0.7.5-1ubuntu16.3" (these modules come from the kernel package, afaik) while the userspace packages are version "0.7.5-1ubuntu16.4". Is this correct?

FWIW, I added this line to /etc/apt/sources.list:

deb http://archive.ubuntu.com/ubuntu/ bionic-proposed restricted main multiverse universe

and then I ran the following to update my system:

$ sudo apt-get update
$ sudo apt-get dist-upgrade

Please let me know if I did anything incorrectly.
