The recipes in this chapter are for the basic maintenance of the Raspberry Pi.
The first few recipes show you how to update the Raspbian operating system and install new software packages, while the last two recipes show you how to access the documentation that is already built into the Raspberry Pi.
Note
The recipes in this chapter work for Debian-based operating systems such as PiNet, Raspbian (recommended by the Raspberry Pi Foundation), and Ubuntu MATE.
Other operating systems, such as Pidora and RISC OS, have their own update and installation mechanisms. For instructions on how to update and install software on these operating systems, visit their respective websites. The See Also section at the end of this recipe has the needed reference links.
After completing the recipes in this chapter, you will be able to update the Raspberry Pi and better understand the built-in documentation.
