Distro? is it updated? do you have all the necessary python packages installed?

Database environment version mismatch. This is telling you that yum is not going to work with Debian. Apt-get or aptitude is for installing in a Debian environment.

This might be helpful:

We need to know what Linux based distro you are using and if you have applied all of the updates to the OS and applications?

Without knowing the distro that you are using we will not know of the chosen package is for your system. Additionally can you tell us the application that you are trying to install and possibly link to the app website so we have a point of reference?

Yum (Yellow dog Updater, Modified) is an automatic updater and package
installer/remover for rpm systems. It automatically computes dependencies
and figures out what things should occur to install packages. It makes it
easier to maintain groups of machines without having to manually update
each one using rpm.
Features include:
* Multiple Repositories
* Simple config file
* Correct dependency calculation
* Fast operation
* rpm-consistent behavior
* comps.xml group support, including multiple repository groups
* Simple interface

I can give everything you want, if you can resolve this problem. thanks.
