I am trying to install netxms 2.0-M4 in debian wheezy. I am getting the following error

apt-get install netxms-server-mysql -f
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 netxms-server-mysql : Depends: netxms-server (= 2.0~M2) but 2.0-M4-1 is to be installed
E: Unable to correct problems, you have held broken packages.
 

Any ideas how to solve this

Thanks in advanced
