Debian

The Pyra will, as shipped, run Debian Jessie, using the official Debian ARMhf repo for most software, with Pyra-specific packages available from a repo on pyra-handheld.com.

A list of software in Debian can be found here (check for armhf as the architecture).

Installing/updating software

To install software on the command line, try searching for a keyword like this: apt-cache search synthesizer. Then run sudo apt-get install zynaddsubfx to install the program. Then type in zynaddsubfx to run it. Try to keep your list of available software updated with sudo apt-get update, and keep your installed programs up-to-date via sudo apt-get upgrade. (For those new to Linux, this is a very quick and painless process compared to other OSes.)

Alternatively, there are beginner-friendly package-managers such as Aptitude (curses) and Synaptic (GUI) for users who feel uncomfortable with command-line tools. Keeping things up to date, searching for available software, and installing it follow the same ideas as above, but with a graphical user interface.

Important note

It's important to keep your Debian software up-to-date as above, but also your DBP software as well.

Reinstalling Debian

If you have somehow completely borked your system, it is possible to reinstall Debian. Pyra-specific images and installer can be found here.
