TrueCrypt mit GUI installieren (Ubuntu 7.10) ( http://www.linewbie.com/2008/01/install-and-configure-truecrypt-with-gui-on-ubuntu-710.html ) 1 Preparation Set up a standard Ubuntu 7.10 system and update it. needs kernel 2.6.24 or later! "Due to a bug in the Linux kernel, your system may stop responding when writing data to a TrueCrypt volume. This problem can be solved by upgrading the kernel to version 2.6.24 or later." 2 Needed Packages First we install some needed packages with the synaptic package manager. * sun-java6-jre * python-pexpect You’ll see this window during the installation - mark the corresponding checkbox and proceed if you agree with the license agreement. Click to enlarge Afterwards check if all went well - open a terminal and enter. java -version The output should look like this: java version “1.6.0_03″ Java(TM) SE Runtime Environment (build 1.6.0_03-b05) Java HotSpot(TM) Client VM (build 1.6.0_03-b05, mixed mode, sharing) 3 Truecrypt 3.1 Installation Open http://www.truecrypt.org/downloads.php within your browser and download the latest stable version for Ubuntu 7.10 (.tar.gz-file containing the .deb-package). Afterwards unpack the .tar.gz-file, switch to the folder with the unpacked files and install the .deb-package with the GDebi package installer (simply double click on the package). Click on “Install Package” to start the installation. Enter the root password. The package and its dependencies are being installed. 3.2 System Configuration Please note, that the following steps (3.2.1 - 3.2.3) can be done automatically by the tcgui installer (step 4). Proceed if you have problems with the tcgui-installer or want to configure the system manually in the first place - otherwise go ahead with step 4. 3.2.1 Users & Groups We have to add the group “truecrypt” to the system and afterwards we add the root-account and our user-account to it. The settings for users and groups are available in the gnome system menu. Enter the root password. Click on “Manage Groups“. Click on “Add Group“. Insert “truecrypt” (without the quotes) as name for the new group, mark the checkbox next to the root and your username and click on “OK“. 3.2.2 Sudo Next we configure sudo in order that TrueCrypt is useable without a password query - open a terminal and enter: sudo visudo Add the following line: %truecrypt ALL=(root) NOPASSWD:/usr/bin/truecrypt It should look like this: # /etc/sudoers # # This file MUST be edited with the 'visudo' command as root. # # See the man page for details on how to write a sudoers file. # Defaults Defaults !lecture,tty_tickets,!fqdn # Uncomment to allow members of group sudo to not need a password # %sudo ALL=NOPASSWD: ALL # Host alias specification # User alias specification # Cmnd alias specification # User privilege specification root ALL=(ALL) ALL # Members of the admin group may gain root privileges %admin ALL=(ALL) ALL %truecrypt ALL=(root) NOPASSWD:/usr/bin/truecrypt To save the changes press CTRL+O (STRG+O on a german keyboard) and hit enter. Close the editor via CTRL+X (STRG+X on a german keyboard). 3.2.3 TrueCrypt Group As a last resort we have to assign TrueCrypt itself to the new group that we created at step 3.2.1. Open terminal and enter: sudo chgrp truecrypt /usr/bin/truecrypt Afterwards we check if all went well - enter: truecrypt -l If you’re NOT asked for a system password and the output looks like this … No volumes mapped … all is fine. TrueCrypt GUI (tcgui) tcgui funktioniert nicht mit Truecrypt 5. Da TrueCrypt in Version 5 über eine eigene GUI verfügt, wird tcgui nicht mehr weiter entwickelt.
