In the past when I have install ubuntu on a ext4 drive, it always get corrupted.

Is there a way to install ubuntu using ZFS, not ext4?

If you look at the screenshot of step 8 at it clearly shows that it's creating a an esp partition as vfat, a swap partition and partitions formatted as zfs. I tried it myself on a vm and this is what my filesystems look like after installation.
Code:

IF I'm not mistaken most installers give you options in the drop down menu of the' partition manager' where you can choose which type of partition you want to create.

The screenshot that f33dm3bits posted confirms that.

Try performing a fresh installation and when it comes time to partition {manual partitioning} use the drop down menu to create the kind of partition (zfs) you want.
Let us know how it goes.
