See the "cannot open 'This': no such pool" while updating grub. This is why you have kernel 5.0 after it and don't have latest zfs after upgrade. You mentionned multiple times a "custom" grub script, does it have "This" somewhere? We don't have any "This" in the distribution script. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1843222 Title: Old Linux version booted after upgrade to Ubuntu 19.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/1843222/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
