HowTo: Stop Ubuntu Checking For Automatic Updates

At work I can’t afford to have my Ubuntu system update and possibly wipe out some important libraries I need, and I get pretty tired of closing the Update Manager every time it decides I need to update so here’s how to stop it:

1. System > Administration > Update Manager
2. Open Settings (in the bottom left corner)
3. Under Automatic Updates
4. Uncheck “Check for updates: “
5. Hit Close and the settings should be saved.
