![]() ![]() You can use the df command to check how much space is available on the SD card ( Figure 1).įigure 1: The df command displays the amount of disk space available. Although, I have upgraded many Debian servers without any complications in the past, I strongly recommend being on the safe side.Īlso, make sure you have sufficient disk space for the upgrade. Preparing the Upgradeīefore upgrading your system, it is a good idea to make a full backup of your SD card, or at least of your personal data and the configuration files you can't afford to lose. You will only have to reboot once – to boot the new kernel and use the new init system (systemd). ![]() All steps can be performed while the Raspberry Pi is running. Bear in mind that you need an Internet connection to upgrade through the package system. Debian 8.0 Jessie updates thousands of software packages, which you can include in your current configuration without having to customize all over again.Ī few shell commands will update the list of packages, upgrade all the packages on your system and, if needed for a package upgrade, install extra packages or remove old ones. Rather than starting over with a new generic system, a package upgrade will build the changes into your existing system. The alternative approach is to upgrade the underlying system through Raspbian's package management tools. Perhaps you have spent some time installing the applications you need for your environment, and you like your files where you have them now – maybe you don't want to start over. However, you might not want to replace your whole operating system. If you are currently running Raspbian Wheezy, the easiest way to upgrade to the Jessie version is to write the latest Raspbian image to a new SD card. (Do the names sound familiar? All Debian editions are named for characters in the movie Toy Story.) ![]() Prior issues of Raspberry Pi Geek have included the previous Raspbian "Wheezy" edition. Raspbian's Jessie edition, which is part of the NOOBS DVD attached to this issue, just appeared recently, although Debian Jessie has been around for several months. It typically takes some time for the Raspbian developers to adapt a Debian release. The latest version, Raspbian Jessie, is based on the Debian 8.0 "Jessie" release. Raspbian versions take their names from the Debian edition on which they are based. The Raspbian developers start with the Debian base files and adapt the file collection, adding libraries, drivers, and other components as necessary to create an environment that is tailored for Raspberry Pi systems and their hardware. The Raspbian operating system used with the Raspberry Pi is an unofficial port of a famous Linux community distribution known as Debian GNU/Linux. ![]()
