That feature is APT pinning. You can achieve "never install" by creating a file in /etc/apt/preferences.d, e.g. /etc/apt/preferences.d/local-blacklist, containing something like Package: unwanted-package other-unwanted-package Pin: release * Pin-Priority: -1 The apt_preferences(5) man page is the reference. As it says, a priority value P < 0 prevents the version from being installed, although I don't think it removes already-installed packages. -- Cheers, Clive
