The problem is that Update Manager refuses to update the system and instead shows a dialog "Requires installation of untrusted packages". This dialog is confusing, because it doesn't explain what the user should do. The only option given is to click "Close" and the update is canceled. The details box is useless since it apparently just lists the packages it was going to update. I have no idea what those "untrusted packages" might be. Should I disable a source? Uninstall a package? The only way I know to go around this is to run apt-get update && apt-get upgrade in the terminal. That shouldn't be the case.
