LTIB is quite old software and initially it was designed to run on redhat-type systems.
It is also possible to run LTIB on ealier versions of Ubuntu with just a minor additional packages installed.
But starting from Ubuntu 12.04, LTIB does not work on Ubuntu without special patch.
Please seach this community for "Ubuntu Ltib patch".
For example, please look the following link:
