It appears to be because since November, we changed partman to create LVM installs without a separate /boot. Unfortunately, /boot is still required for LVM+crypto, as grub2 by itself can't load cryptodisks (unless the option is enabled, that is), and doing so would make it necessary to unlock the cryptodisk twice -- once for grub, and another time for the kernel.
For now, let's just make sure crypto still uses a /boot partition. ** Also affects: partman-auto-lvm (Ubuntu) Importance: Undecided Status: New ** Changed in: partman-auto-lvm (Ubuntu Zesty) Status: New => Triaged ** Changed in: partman-auto-lvm (Ubuntu Zesty) Importance: Undecided => Critical ** Changed in: partman-auto-lvm (Ubuntu Zesty) Assignee: (unassigned) => Mathieu Trudel-Lapierre (cyphermox) ** Changed in: partman-auto-lvm (Ubuntu Zesty) Milestone: None => ubuntu-17.02 ** Changed in: grub-installer (Ubuntu Zesty) Status: Triaged => Invalid ** Also affects: ubiquity (Ubuntu) Importance: Undecided Status: New ** Changed in: ubiquity (Ubuntu Zesty) Status: New => Triaged ** Changed in: ubiquity (Ubuntu Zesty) Importance: Undecided => Critical ** Changed in: ubiquity (Ubuntu Zesty) Assignee: (unassigned) => Mathieu Trudel-Lapierre (cyphermox) ** Changed in: ubiquity (Ubuntu Zesty) Milestone: None => ubuntu-17.02 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1659448 Title: grub fails to install bootloader for zesty LVM with Encryption To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1659448/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
