Not enough information to be sure but my suggestion is to try this;
Code:
sudo apt-get purge krb5-kdc krb5-admin-server
Then try re-installing.
If you get errors while trying to purge those packages, then run;
Code:
sudo apt-get install --fix-missing
Note that I'm not familiar with the package you're trying to install so there might be something sneaky going on there. For example, you may simply need to manually configure the server.
It looks like the package installed okay but needs to be configured properly.
