Just press the 'Mark' button to mark them for upgrade note that the upgrade is not done right away: While you are there, you might as well upgrade what can be upgraded to the latest version, by clicking on 'Mark All Upgrades': The packages are split into sections, starting 'Amateur Radio', 'Base System' etc.: To do this, choose 'Reload Package Information' from the Edit menu, or press 'Ctrl+R': You'll see a list of packages on your Raspberry Pi that can be installed, but first we need to update the list of packages to the latest ones. The default password is usually 'raspberry': You will be prompted for a password as Synaptic needs to run as the 'root' user 'pi'. Synaptic is started from the Preferences menu: If it is not started, start it with 'startx' in the terminal. You need to be in the Desktop mode on your Raspberry Pi. Open a terminal window and type the following:Īnswer 'yes' to any questions that are asked during installation. We're going to do the latter using 'synaptic'.įirst, we're going to have to install 'synaptic'. One is via the command line ('apt-get', in a terminal window), while the other has a user interface. There are two ways to install more applications, or 'packages' as they are called in the Linux world. There are a few applications that have been written by the Raspberry Pi community, but this is only a really small selection of what is available.
You'll find it under the Internet Menu when you're running the GUI on the Raspberry Pi. The Raspberry Pi Foundation has created the 'Pi Store', similar to the Play Store or App Store on your phone. The list will probably scroll off the screen, and most of it is unlikely to mean anything to you! Don't worry - there's more. You can find out what else is there by running the following command in a terminal window: Obviously, you can find out what is there by looking at what is in the Menu, under the headings of 'Programming', 'Internet', 'Games', and 'Accessories'. Unless you are going to develop your own applications, you probably don't need to worry about these.īut what you probably do want to know is 'what is installed on my Raspberry Pi' and 'what else can I install'. Linux programmers don't like writing code when they can use code that other people have already written and tested, so there are lots and lots of 'libraries' that have been written and shared by applications. Your Raspberry Pi has lots of applications already installed, like Minecraft, Mathematica, and the browser.Īnd there are a lot of 'libraries'.
