    Ubuntu 23.10 Server Installation with TPM-Backed FDE?

    Is it possible to install 23.10 Server with the TPM-backed Full Disk Encryption feature yet?

    Sort of... Install from the Ubuntu Desktop installer with those installer options.

    After the install finishes, and reboots, after booting... Press the keys <Cntrl><Alt><F4>... Login with your credentials...
    Code:
    sudo apt update
    sudo apt remove --purge ubuntu-desktop
    sudo apt install ubuntu-server
    Edit the netplan yaml file from /etc/netplan/ and replace the renderer from Network Manager to networkd. Make any other changes. Save and exit
    Code:
    sudo systemctl stop NetworkManager
    sudo systemctl disable NetworkManager
    sudo systemctl mask NetworkManager
    sudo systemctl enable systemd-networkd
    sudo systemctl enable systemd-networkd
    sudo systemctl start systemd-networkd
    sudo netplan generate
    sudo netplan apply
    And there you go.

    OR... From the 23.10 Server edition Installer LiveUSB, you go go over to a system prompt from the Help button, and do it all manauly. The how to do it is well ducmented, and you can do a better job, by creating the LUKS containers, setting your own passphrases, and enrolling the key to the TPM, while adding your own secondary recovery keys in the keyslots, add a keyfile for any other added LUKS partitions (like home or data) and avoid the bug report I have file on the installer for that install option: https://bugs.launchpad.net/ubuntu-de...r/+bug/2039741

    With that installer's partitioner, it is volume manager and filesystem aware, so you can then exit the system prompt, back to the installer, use "other" to get to the partitioner, where you can connect the mounts to where you want them, then continue the installation.

    Either way.
