Public bug reported: Long story short, trying to install 19.10 with ZFS root and it keeps failing saying that /target is unavailable. I figured out the real problem under it all was that it was getting an error when running:
/usr/share/ubiquity/zsys-setup init When that ran it end of the relevant log was: + format_disk /dev/sda 2 6 7 4 + disk=/dev/sda + partgrub=2 + partbpool=6 + partrpool=7 + ss=4 + partswap=5 + partext=3 + sfdiskopts= + partprefix=/dev/sda + echo I: Formatting disk /dev/sda with partitions grub:2 ext:3 bpool:6 rpool:7 I: Formatting disk /dev/sda with partitions grub:2 ext:3 bpool:6 rpool:7 + [ false = true ] + sfdisk -l /dev/sda + grep ^/dev/sda2 + awk {print $2} + start=4096 + cat + cat /tmp/sfdisk.cfg + sfdisk /dev/sda Checking that no-one is using this disk right now ...

If you look into the zsys-setup source you'll notice that there are two possible configs that can be passed into sfdisk. One is chosen if there is EFI detected and the other if not. My machine doesn't have EFI enabled, but the disk is GPT, so it needs that configuration for the drive. I believe, and I'm no drive expert, that you need to look for the label type to make this determination. For me the output of: sfdisk -d /dev/sda includes a "label: gpt" which I believe can be used to determine which disk format config should be used. ** Affects: ubiquity (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1858065 Title: zsys-setup is detecting drive format typing using EFI availability To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1858065/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
