I did want to have @ and @home. When installing previous ubuntu releases, I usually kept the btrfs partition with the @home subvolume, and moved the @ one out of the way, and the installer would create the new @ subvol for root, and reuse @home.
This my current layout (on eoan) is the following: /dev/sda1 EFI -> /boot/efi /dev/sda2 ext2 -> /boot /dev/sda3 LUKS volume, containingt the "ubuntu" LVM PV with following LVs: "swap" -> swap "root" -> btrfs with "@" and "@home" Before reinstalling, I just moved "@" to "@-eoan" and manually recreated the same layout, picking /dev/ubuntu/root as btrfs filesystem mounted at /, without formatting. The installer creates the @ subvolume and reuses the @home one. Since this attempt, I've been unable to test the install again because of #1867065 which doesn't get me past boot. ** Changed in: ubiquity (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1862503 Title: Installer crashed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1862503/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
