====== Prepare your GNU/Linux system for the cp4j ======

To install software under GNU/Linux systems is fairly straightforward.

===== Short Remarks =====

With this approach, you 'll install or update the following software at once:

  * [[https://gnupg.org/|GnuPG]] - The Gnu Privacy Guard - A free tool for secure communication and data storage.
  * GnuPG2 - Another free GnuPG version.
  * [[https://www.gnupg.org/related_software/gpa/screenshots.html|GPA - The GNU Privacy Assistent]] - A free graphical program for key management.
  * [[https://pidgin.im/|pidgin]] - A free multi-platform chat-client.
  * [[https://otr.cypherpunks.ca/|pidgin-otr]] - A free plugin, that keeps your chats private.
  *[[http://keepass.info/|keepass]] - A free program for secure password management.
  * [[https://en.wikipedia.org/wiki/Mozilla_Thunderbird|Thunderbird]] or [[https://en.wikipedia.org/wiki/Icedove#Icedove|Icedove]] - A free e-mail client, that interacts with enigmail (see: below).
  * [[https://enigmail.net/home/index.php|Enigmail]] - A free plugin, that automatically decrypts and verifies your e-mail.

If the software already exists on your system, it simply updates or doesn't get installed.
Files like private keys or public keys won't get overwritten. 
===== Ubuntu and *buntus =====

On distributions like Ubuntu, Kubuntu, Xubuntu or Mint, do the following:

  - Open a terminal window
      * You can do this by pressing CTRL+ALT+T on your keyboard simultaneously, or 
      * by clicking:  Applications > Accessories > Terminal
  - Type: <code>sudo apt-get update</code>
  - It will ask for your password. Type it in and press ENTER to continue.
  - Now type: <code>sudo apt-get install gnupg gnupg2 gpa keepass2 pidgin pidgin-otr thunderbird enigmail</code>
  - Perhaps it will ask for your password again. If not, just press ENTER to continue. If it does, type it, and then press ENTER to continue.
  - Press y to continue. Let the machine do the installing.
  - Type: <code>exit</code>

Congratulations. Your software is now either updated or freshly installed. Now participate in the next cryptoparty to get used to using it. Have fun!
