Your upgrade is done, but for the record, installing the HWE kernel

Also, once you're sure the HWE kernel is working, you'll probably want
to remove the linux-image-generic package so you're not

ZFS 0.7.9 was released in Cosmic (18.10). You could update to Cosmic.
Alternatively, on 18.04, you can install the HWE kernel package: linux-

I noticed that the status of this bug has been changed to `fix
released`. Where/how has the fix been released and how does one patch a
