It's a feature that was there before (encrypting /home) but is no longer supported.
As for full disk encryption, you still have the option of doing the partitioning yourself; we indeed to not currently provide an option to do resizing *and* disk encryption. Marking as Wishlist / Triaged, since these feature requests are fairly well understood. ** Changed in: ubiquity (Ubuntu) Status: New => Triaged ** Changed in: ubiquity (Ubuntu) Importance: Undecided => Wishlist -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1799550 Title: No way to encrypt at partition level (dual boot) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1799550/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
