The W prefix means a warning, not an error. It's harmless, and basically 
unavoidable with reprepro-managed Debian repositories using snapshots.

In the general case, it will work.

But downgrading with Apt is an absolute pain in the ass - you will 
likely have better results by uninstalling everything Mono-related THEN 
using the snapshot than trying to downgrade from one version to the other.
