Important hint

The monitoring software TKmon is no longer being developed further and the Thomas-Krenn call-home service has also now been switched off.

Installation Ubuntu 12.04

In the following example we will be using Ubuntu 12.04.1 installation media. This will ensure that the core version 3.2 is used (instead of newer core versions by the Ubuntu 12.04.2 LTS Enablement Stack):

1. Ubuntu 12.04.1 installation (incl. OpenSSH-Server)
   • Language (F2): English, Keymap (F3): German
   • For installation on the Low Energy Server during the installation follow this set of core parameters (via F6) - see also Ubuntu 12.04 Kernel Parameters for the Low Energy Server:

     acpi=force reboot=acpi psb_gfx.blacklist=yes

   • Username: tkmon
2. After the installation, and depending on which kind of installation configure Locales in Ubuntu:

   sudo locale-gen de_DE.UTF-8

3. Loading System Updates:

   sudo apt-get update

   sudo apt-get dist-upgrade

   sudo apt-get clean

   sudo reboot
