** Description changed: In today's world, especially with the likes of the EU's GDPR and the many security fails, Ubuntu installer needs to support full-system encryption out of the box. This means encrypting not only /home but also both root and /boot. The only parts of the system that wouldn't be encrypted are the EFI partition and the initial Grub bootloader, for obvious reasons. It should also not delete other installed systems unless explicitly requested. On top of this, the previous method of encrypting data (ecryptfs) is now considered buggy, and full-disk encryption is recommended as an alternative. Unfortunately, the current implementation of full-disk encryption wipes any existing OS such as Windows, making the implementation unusable for most users. Now, using LUKS and LVM, it is already possible to have full-disk encryption (strictly, full-partition encryption because it leaves any existing OS alone), while encrypting /boot. Reference: https://help.ubuntu.com/community/ManualFullSystemEncryption ... but with one major limitation: Grub is incorrectly changed after an update affecting the kernel or Grub, so that a manual Grub update is required each time this happens (this is fully covered in the linked instructions). If the incorrect Grub change is fixed, it should be (relatively) simple to support full-system encryption in the installer. Further information (2018-08-17): The NCSC recommends, "Use LUKS/dm-crypt to provide full volume encryption."
