/etc/cobbler/version has incorrect format, it should be in YAML.. Example:

builddate: Thu Jan 30 21:42:10 2014
gitdate: Mon Dec 9 11:08:16 2013 -0800
gitstamp: 2181fa3
version: 2.5.0
version_tuple: [2, 5, 0]

It is possible you'll have conflicts with other files. I'd recommend 
backing up important data and making a a clean installation.
