Thank you for your bug report. Could you describe what you were doing exactly and what image you using?

From the report
 LiveMediaBuild: Ubuntu 19.10 "Eoan Ermine" - Beta amd64 (20190926.1)

That image is some weeks old, could you try with the current daily?

Hello Sebastien!

What happened was this: I downloaded the beta ISO from 19.10. When trying to install it by formatting the disk in ZFS, I noticed that the option has not been available in the installer.

I ran an apt update and apt full-upgrade and waited for the update to finish. After that, I proceeded with the installation and selected the entire disk to install with the ZFS partition. Upon reaching the installer part of the grub, the installation broke down.

I don't understand much about it, but I think it's some compatibility issue between grub and ZFS.

Sorry, I forgot to complete the message: I will download the latest ISO and try to install it again. I'll be back to report if it worked or not. Many thanks!

Hi. I have downloaded the new ISO and now Ubuntu installs perfectly. You can close this issue. ;)
