How do I install new software?

Question

I am aware that Linux distributions usually have 'package managers' to allow me to download and install software from the command line and that I should also be able to download and compile source code from the web but I am not sure about how best to do either of these things on the Raspberry Pi.

Answer 1

Debian

APT is the package manager under Debian, for Raspberry Pi or any other system. The command line tool curl is installed in this example.

You need to be connected to the Internet.

If you haven't done so recently it is worth running,

sudo apt-get update

This updates the list of packages that are available to apt-get.

Then use apt-cache to search for the package that you want to install, in this case,

apt-cache search curl

Every package name or description with the word 'curl' in it will be displayed in a list. This is useful in cases where you are not sure as to the exact name of the package that you want to install.

Once you have the name of the package that you want, install it as follows,

sudo apt-get install curl

If you're not sure what you're looking for or just wish to browse through what's available, you can alternatively use the menu-driven tool Aptitude:

sudo aptitude
