I have verified using the upgrader tarball for noble-proposed. To create a VM with Ubuntu Desktop TPM FDE, I did the following:
$ lxc storage volume import default ~/downloads/ubuntu-23.10.1-desktop-amd64.iso 23.10-desktop --type=iso $ lxc init --empty --vm lxd-mantic-fde -c limits.memory=6GiB -c limits.cpu=4 -d root,size=32GiB $ lxc config device add lxd-mantic-fde iso-volume disk pool=default source=23.10-desktop boot.priority=10 $ lxc config device add lxd-mantic-fde tpm tpm $ lxc start --console=vga lxd-mantic-fde I went through the installer, and selected TPM FDE from advanced features. Then, after the installation, I ran the following in the VM: ubuntu@ubuntu:~$ wget http://archive.ubuntu.com/ubuntu/dists/noble-proposed/main/dist-upgrader-all/24.04.18/noble.tar.gz --2024-05-17 11:02:12-- http://archive.ubuntu.com/ubuntu/dists/noble-proposed/main/dist-upgrader-all/24.04.18/noble.tar.gz Resolving archive.ubuntu.com (archive.ubuntu.com)... 185.125.190.39, 91.189.91.82, 185.125.190.36, ...
