If you know how to use it, don't care for the following explanation for begginers: to edit text files on a terminal using the Vi command, follow this example: Since you are on a terminal with no gedit or something like that, you will need a pure text editor such as Vi. This is done by modifying /etc/apt/sources.list, uncommenting all the “deb” repositories. Part 2: Cryptography software installationĬonfigures your apt to use all the optional repositories which come with Ubuntu. Just ignores the alert about not having a swap partition and keep walking. Note that it is not absolutely necessary to have an exclusive /home partition, so this is optional since you can have only one partition for a whole encrypted system.
Set these partitions in the installer option for filesystem as "do not use the partition".
In addition, I created two more spaces to hold my future encrypted root and /home partitions, so as the following: A complete Ubuntu installation requires at least 2.4 GB. Mark that 512 MB is really the shortest size you can set for a server type of installation. Install Ubuntu with server profile with the following initial partitioning scheme: Mark that I am not a connoceur on the subject or even a crypto freak, I just can say that this worked for me. The default algorithm is AES (aes-cbc-plain) with 256bits key. This fully encrypted filesystem method employs dm-crypt, linux kernel's devmapper and cryptography. The old root which I used in the beginning is turnt into a swap partition. Since Ubuntu installer does not support yet this option, this process concerns, first, installing Ubuntu on a temporary partition and then, inside that instalation, preparing all the encrypted partitions for the OS. This is the way I did to get an Ubuntu 5.10 (Breezy) with full encrypted file system: root (/), home and swap. Ubuntu, Full encrypted system root, home, swap Full encrypted system: root, home, swap
