On occasion, I'm able to interchangeably use a suggest apt command with apt-get instead. That's most likely not 100%, though. Just means I got lucky a time or ten. :) > My question was if apt (or apt-get) dist-upgrade was equivalent of apt > (or apt-get) full-upgrade? I can't directly answer your question, but I *could* at least grab something from "man". :) >From "man apt-get" (I only found dist-upgrade referenced there): dist-upgrade : dist-upgrade in addition to performing the function of upgrade, also intelligently handles changing dependencies with new versions of packages; apt-get has a "smart" conflict resolution system, and it will attempt to upgrade the most important packages at the expense of less important ones if necessary. The dist-upgrade command may therefore remove some packages. The /etc/apt/sources.list file contains a list of locations from which to retrieve desired package files. See also apt_preferences(5) for a mechanism for overriding the general settings for individual packages. >From "man apt" (I only found full-upgrade referenced there): full-upgrade (apt-get(8)): full-upgrade performs the function of upgrade but will remove currently installed packages if this is needed to upgrade the system as a whole. *hm.* :) Kind of sounds at least very similar, just that description is not as verbose for "man apt". The "man apt-get" blurb helps *me* feel a little more confident that I *might* better understand what *might* be about to happen if I go that route. With respect to "man apt-get" specifically suggesting/highlighting "apt_preferences(5)"... the fun would be in determining what individual packages might be direly affected such that an overriding mechanism would be necessary. "apt_preferences(5)" wasn't likewise specifically mentioned directly related to "full-upgrade" in "man apt", but there was a helpful bottom-of-the-page reference that did still point users toward "man 5 apt_preferences". It's then up to us users to heed those additionally suggested manpages as potentially being important to whatever we may be trying to accomplish. :) Cindy :) -- Cindy-Sue Causey Talking Rock, Pickens County, Georgia, USA * runs with duct tape *
