[Bug 804382] [NEW] "Requires installation of untrusted packages"-dialog is confusing

[juzzlin]

Public bug reported:

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.
