Ubuntu 15.10 fulldisk encryption howto
The following howto has been partly stolen from somewhere else . I adapted it to my situation. The main setup is the same: The whole installation (swap + root fs + home) should reside in a single encrypted container so that at boot we only have to provide one password and hibernate is encrypted too. Only the bootloader is unencrpyted.
