The easiest way to manage installing, upgrading, and removing software is using APT (Advanced Packaging Tool) from Debian. If a piece of software is packaged in Debian and it works on the Raspberry Pi’s ARM architecture, it should also be available in Raspbian.<\/p>\n
To install or remove packages you need root user permissions, so your user needs to be in sudoers<\/em><\/strong> or you must be logged in as root<\/em><\/strong>. Read more about users and root.<\/p>\n To install new packages, or update existing ones, you’ll need an internet connection.<\/p>\n Note that installing software uses up disk space on your SD card, so you should keep an eye on disk usage and use an appropriately sized SD card.<\/p>\n Also note that a lock is performed while software is installing, so you can’t install multiple packages at the same time.<\/p>\n APT keeps a list of software sources on your Pi in a file at \/etc\/apt\/sources.list. Before installing software, you should update your package list with apt update:<\/p>\n Typing this command should inform the user how much disk space the package will take up and asks for confirmation of the package installation. Entering Y (or just pressing Enter, as yes is the default action) will allow the installation to occur. This can be bypassed by adding the -y flag to the command:<\/p>\n Installing this package makes tree available for the user.<\/p>\n Using an installed package<\/p>\n tree is a command-line tool which provides a visualisation of the structure of the current directory, and all its contents.<\/p>\n Typing tree runs the tree command. For example:<\/p>\n Typing man tree<\/em><\/strong> gives the manual entry for the package tree<\/strong><\/em>. Uninstalling a package with APT<\/p>\n Remove<\/strong><\/p>\n You can uninstall a package with apt remove:<\/p>\n The user is prompted to confirm the removal. Again, the -y flag will auto-confirm.<\/p>\n Purge<\/strong><\/p>\n You can also choose to completely remove the package and its associated configuration files with apt purge:<\/p>\n If software updates are available, you can get the updates with<\/p>\n and install the updates with<\/p>\n which will upgrade all of your packages. To upgrade a specific package, without upgrading all the other out-of-date packages at the same time, you can use<\/p>\n (which may be useful if you’re low on disk space or you have limited download bandwidth).<\/p>\n You can search the archives for a package with a given keyword with apt-cache search:<\/p>\n You can view more information about a package before installing it with apt-cache show:<\/p>\n The easiest way to manage installing, upgrading, and removing software is using APT (Advanced Packaging Tool) from Debian.
