ZFS Installer refuses to install the boot loader on both disks

[BertN45]

I installed Ubuntu Mate 19.10 on ZFS in Virtualbox on sdb, while sda has Ubuntu 19.10 on ext4 with both zfsutils-linux and zfs-initramfs installed. The installer refused to install a boot loader on both sda and sdb, but after booting from ext4 and:

    updating /etc/default/grub
    update-grub and grub-install /dev/sda

I have a nice dual boot system in Virtualbox :slight_smile:

I think the installer should have installed the boot loader.

I had a similar experience doing a clean install with the Experimental ZFS option. This happened repeatably for devices /dev/sda and /dev/sda1, i.e., the installer refused to install to either device and I ended up manually fixing this issue from chroot operations from the livecd.

Just to clarify, my experience referenced in comment #1 was with the Ubuntu Desktop daily-live CD posted at http://cdimage.ubuntu.com/ubuntu/daily-live/20191008/ running under Oracle Virtualbox v6.012.
