It provides the same functionality as the specialized APT tools, like apt-get and apt-cache, but enables options more suitable for interactive use by default. Most used commands: list - list packages based on package names search - search in package descriptions show - show package details install - install packages reinstall - reinstall packages remove - remove packages autoremove - Remove automatically all unused packages update - update list of available packages upgrade - upgrade the system by installing/upgrading packages full-upgrade - upgrade the system by removing/installing/upgrading packages edit-sources - edit the source information file satisfy - satisfy dependency strings See apt(8) for more information about the available commands. Configuration options and syntax is detailed in apt.conf(5). Information about how to configure sources can be found in sources.list(5). Package and version choices can be expressed via apt_preferences(5). Security details are available in apt-secure(8). This APT has Super Cow Powers. stack@reiji-PowerEdge-R740:~$ git Command 'git' not found, but can be installed with: apt install git Please ask your administrator stack@reiji-PowerEdge-R740:~$ sudo apt install git Reading package lists...
