I think this is a dependency issue. with apt-get update && apt-get -y install zfsutils-linux" I get the same error "*** Please make sure the kmod ...", but the kernel module will eventually build after a 10m timeout(spl-timeout=600)
with apt-get update && apt-get -y install spl spl-dkms && apt-get -y install zfsutils-linux the kernel module will be build without delays. as attachment there is a simple script which illustrates the Issue
zfs-test.sh
Description: application/shellscript
