ODN .DEB package, among other things depends on apach2 package. It also specifies concrete dependency on apache2-mpm-worker.
But this particular dependency clashes with for example Plex package, which relies on apache2-mpm-prefork: apache2-mpm-worker conflicts with apache2-mpm-prefork, they can't be installed at the same time thus it is hard to install both ODN and Plex at the same time on one machine.
So, in order to lower chances of conflicts between ODN and other packages, please try removing particular dependency on apache2-mpm-worker.
