DESCRIPTION apt-get is the command-line tool for handling packages, and may be considered the user's "back-end" to other tools using the APT library. Several "front-end" interfaces exist, such as aptitude(8), synaptic(8) and wajig(1). [...] 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. [...] install install is followed by one or more packages desired for installation or upgrading. Each package is a package name, not a fully qualified filename (for instance, in a Debian system, apt-utils would be the argument provided, not apt-utils_1.2.10_amd64.deb). All packages required by the package(s) specified for installation will also be retrieved and installed. [...] remove remove is identical to install except that packages are removed instead of installed. Note that removing a package leaves its configuration files on the system. [...] purge purge is identical to remove except that packages are removed and purged (any configuration files are deleted too). [...] autoremove (and the auto-remove alias since 1.1) autoremove is used to remove packages that were automatically installed to satisfy dependencies for other packages and are now no longer needed [...]
