After playing a few days on the gconf-editor (Linux like regedit) I learned how to do it and it wasn't that difficult.
=====If you have gconf-editor installed=====
Steps:
- Open up the Terminal and type in gconf-editor
- Click on apps > update-manager > untick “check_dist_upgrades”
- Exit out gconf-editor of then logout of Ubuntu.
- The Update Manager should not ask you to upgrade again!
Steps:
- Enter this into the Terminal: sudo gedit ~/.gconf/apps/update-manager/%gconf.xml
- Enter your password in the terminal.
- Add this code under <gconf> <entry name="check_dist_upgrades" mtime="1309071139" value="false"/>
- Save and exit then logout of Ubuntu.
- The Update Manager should not ask you to upgrade again!
