====== Install Ubuntu 20.04 with Full Disk Encryption ======

**Warning: It's critical that you do NOT reboot the installed system before copying the recovery key somewhere safe. Else it will get lost in the ether, never to be found again.**

This requires a network connection during the installation so you have a place to copy the LUKS recovery key to.

For the most part, you can proceed with the Ubuntu MATE installation as usual: select your languages and keyboard layout, Ubuntu standard install (un-select install updates during install to avoid getting ahead of our local mirror).

Raw guide:
  * for the drive install page you gotta select "Erase disk and Install Ubuntu MATE"
  * Click advanced features
  * Select LVM
  * Select full drive encryption
  * Click Continue, then Continue again (be patient, the encryption setup takes a couple minutes to finish)
  * Enter s password for LUKS... do it again.
  * Check the save a key box
  * Click Continue
  * Finish installation as usual (timezone and user)
  * BEFORE YOU REBOOT: copy the /home/ubuntu-mate/recovery.key file somewhere
  * After the key is copied you can reboot and continue like normal with the Ubuntu install
