I want to upgrade to ubuntu 12.10 from 12.04. But I am not able to do it. I don't see upgrade tab in download manager. These are the steps I followed:
- Open Update manager
- Click on settings
- Click on updates tab
- Notify me of a new version: "for any new version".
After doing this, I even restarted the machine, still I don't see upgrade tab in download manager. Plz help.
