Every time launch update-manager does:
1. Search packages information
2. Show packages that needs update
The information that collects it's from "apt" cache, but If I need the last information (for example, If we have many packages updates in a day) I must update the repositories info.
I suggest that update-manager does:
1. Update the repositories information
2. Search packages information
3. Show packages that needs update
