MongoDb Upgrade from 2.6 to 3.0 Issue For some reasons I cannot install MongoDb 3.0 version. What am I missing?
It doesn't look like MongoDB provides a repo for Saucy: http://repo.mongodb.org/apt/ubuntu/dists/

So if you installed via Ubuntu-provided repository you have a few options:


Remove the RPM and install via binaries
Upgrade to Trusty
Wait for Ubuntu to update its repo.
