ZFS broken after upgrading to 15.10

Upgraded earlier from 15.04 to 15.10, now my ZFS system won't mount. Checking for updates comes up with "Unable to locate package ubuntu-zfs" checking the PPA here it seems that the PPA for 15.10 is missing ubuntu-zfs.

Does anyone have a work around for getting my zpool to work again. I've tried using ZFS-Fuse but it's running an older version than when I was using ubuntu-zfs.

Any help in getting my ZFS system working again would be appreciated.

Solution 1:

For those who encounter the following errors,

The following packages have unmet dependencies:
zfsutils-linux : ***Depends: zfs-doc (= 0.6.4.2-0ubuntu1) but 0.6.5.3-1~wily is to be installed***
                  Depends: libnvpair1linux but it is not going to be installed
                  Depends: libuutil1linux but it is not going to be installed
                  Depends: libzfs2linux but it is not going to be installed
                  Depends: libzpool2linux but it is not going to be installed
                  Recommends: zfs-dkms but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

This is most probably due to having ppa:zfs-native/stable in your apt source repository. Remove the ppa:zfs-native/stable from your apt repository, and re-run apt-get update. Then proceed to install via apt-get install zfsutils-linux

That should fix it for you.

Solution 2:

Ubuntu 15.10 has ZFS support out of the box. Try to install zfsutils-linux which builds the native kernel modules for Linux (zfs-dkms).

$ apt-get install zfsutils-linux

Solution 3:

I had this problem as well after an upgrade from Ubuntu 15.04 to 15.10. I also got the unmet dependencies issue that TL-Aiyor and others listed. Removing the PPA did not work for me though. I had to purge all (probably could have just purged zfs-doc but just purged everything) zfs from the system and re-install.

apt-add-repository --remove ppa:zfs-native/stable
zpool export tank
apt-get purge zfs*
apt-get autoremove
apt-get install zfsutils-linux
zpool import tank

Everything after that went just dandy.
