When it comes to apt-get, the documentation is equally applicable to all distributions based off of debian. So there is no point of restricting your google searches to site:debian.org . Here is what I found by googling for "apt-get upgrade vs update" and the first hit http://askubuntu.com/questions/94102/what-is-the-difference-between-apt-get-update-and-upgrade provides the answer to your question. Also here are the relevant sections in the man page $ man apt-get ... update update is used to resynchronize the package index files from their sources. The indexes of available packages are fetched from the location(s) specified in /etc/apt/sources.list. For example, when using a Debian archive, this command retrieves and scans the Packages.gz files, so that information about new and updated packages is available. An update should always be performed before an upgrade or dist-upgrade. Please be aware that the overall progress meter will be incorrect as the size of the package files cannot be known in advance. upgrade upgrade is used to install the newest versions of all packages currently installed on the system from the sources enumerated in /etc/apt/sources.list. Packages currently installed with new versions available are retrieved and upgraded; under no circumstances are currently installed packages removed, or packages not already installed retrieved and installed. New versions of currently installed packages that cannot be upgraded without changing the install status of another package will be left at their current version. An update must be performed first so that apt-get knows that new versions of packages are available. hope that helps -- Kamaraju S Kusumanchi | http://raju.shoutwiki.com/wiki/Blog -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
