I have this error too, but it seems that you no longer need the zfs- linux dkms packages on 16.04. Ubuntu ships the ZOL module with the main kernel package. So the fact it wont build is irrelevant. Unless you specifically need to build it out of tree???
The version currently included is: 0.6.5.6-0ubuntu15 http://kernel.ubuntu.com/git/ubuntu/ubuntu- xenial.git/commit/?id=8e543f2fd146981d88366f93d2d0b9453e7e507e And the in-tree version was patched to work with posix_acl changes, which have broken then DKMS build. See last patch in the commit here: http://kernel.ubuntu.com/git/ubuntu/ubuntu- xenial.git/commit/?id=37d3c4d67f90135a44c2d23e4546f31dd5b61a44 I'm going to remove the DKMS version from my system, but it's a simple fix for those who want to keep it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1660416 Title: zfs-dkms 0.6.5.6-0ubuntu14: zfs kernel module failed to build To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1660416/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
