I'm running Ubuntu 14.04 LTS and I have a Western Digital external hard drive (Passport Ultra) mounted. I want to encrypt the entire drive. WD has Windows and Mac utilities available, but nothing for Linux/Ubuntu.
I have consulted Ubuntu help and found one article (https://help.ubuntu.com/community/EncryptedFilesystemsOnRemovableStorage), but the material appears to be seriously dated. The article recommends installing a utility, Gnome-disk-utility
, but my attempt to do so failed owing to dependency problems which I am not sufficiently knowledgeable even to attempt to resolve. The help article also gives a routine for encrypting entirely from the terminal, but I am hesitant to try because apparently it hasn't been tested since version 10.04.
So my questions are:
is there a Gnome-disk-utility package available for 14.04 (and if so, where); or failing that
is the command line routine reliable for 14.04?
Any help would be much appreciated.
