According to this site Chrome's current stable version for Linux is 25.0.1364.172 since March 12 (2013). It's the 18th now and I still have version 24.0.1312.52 in my system. I've tried:
sudo apt-get upgrade google-chrome-stablebut it says there's nothing to upgrade. What's the deal here?

The answer was given here. I had to manually re-enable Chrome's PPA that had been disabled automatically after upgrading from 12.04 to 12.10. For some reason the software origins GUI wouldn't let me change it there so I had to edit the PPAs files by hand.
