This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

sudo apt-get update
sudo apt-get upgrade

Or just refresh update manager.

It's part of the normal release system (v8 is in both ubuntu-updates and ubuntu-security) so you should get it. If you're still not getting it, there's likely a problem with your updates in general.

Running sudo apt-get update manually in a terminal should display any errors.

Click the system/power cog and click "Software Up to Date" or "Updates Available" to bring up the Update Manager.
