I believe this because apt-get update resolved this and it's not a bug per-se with zfs. Thank you for reporting this issue.

But I'm pretty sure I need the newer 0.8.1-1ubuntu14 package because the previous version 0.7.12-1ubuntu5 zfs command fails: zfs: symbol lookup error: zfs: undefined symbol: libzfs_dataset_cmp When I try to ask for the kept back page to be upgraded: # apt dist-upgrade -y zfsutils-linux The following packages have unmet dependencies: zfsutils-linux : Conflicts: insserv (< 1.18) but 1.14.0-5ubuntu3 is to be installed E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. I really don't understand the <1.18 when 1.14.0 looks less than 1.18. Is there a workaround? whoa... on a whim, I tried apt-get instead of apt. It seems to have worked. $ sudo apt-get install zfsutils-linux I'm filing this bug so that others may find this work around.
