- Now, click on the Settings button present in the lower-left corner of the Update Manager window.
- The Settings button will open Software Sources dialog box. Click on the Updates tab. In the tab, come to the section that says, Notify me of a new Ubuntu version. Change this option to For Any New Version and DO NOT change any other settings here.
- After you’ve changed the option, you’ll be prompted to type your Ubuntu account’s password to confirm changes. Close Software Sources, also close Update Manager. Then reopen Update Manager again. You’ll now see an option to upgrade to Ubuntu 12.10.
