What version of MongoDB is installed on Ubuntu

Hi I'm a bit of a shell n00b. Can anyone tell me how I would check the version of MongoDB that is installed on my Linux Ubuntu machine? I see that my MongoDB shell version: 1.2.2 so Im pretty sure that MongoDB itself is out dated too. And does anyone know of any 'How to update MongoDB' docs? I find mongodb.org to be a bit confusing. Please and thank you. ---------------------------- Ok if I use db.version() inside of mongo shell it says 1.2.2 If I $ mongod --version I get this: db version v1.2.2, pdfile version 4.5 Wed Oct 16 10:28:22 git version: nogitversion I ran sudo apt-get update sudo apt-get install mongodb and get sudo apt-get install mongodb Reading package lists... Done Building dependency tree Reading state information... Done mongodb is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 179 not upgraded. mongod --version db version v1.2.2, pdfile version 4.5 Wed Oct 16 10:31:07 git version: nogitversion So why isn't it updating? Is apt-get pointing at the wrong repo / source?
