Over and above -y, --force-yes does the following: * Allow installation of unauthenticated packages. (If you need this, you should use --allow-unauthenticated instead, which is narrower.) * Force upgrading of held packages. * Force downgrading packages. * Force removal of essential packages. I have a hard time seeing how you'd ever have held packages or packages that need downgrading (though if it is actually realistically possible and not just a theoretical edge case then I suppose that might justify using --force-yes), and removing essential packages is an actively harmful thing that could easily cause hard-to-diagnose failures later. -- Colin Watson [cjwat...@canonical.com] _______________________________________________ Mailing list: https://launchpad.net/~launchpad-dev Post to : launchpad-dev@lists.launchpad.net Unsubscribe : https://launchpad.net/~launchpad-dev More help : https://help.launchpad.net/ListHelp
