Zynthian Updating

Important notice

Zynthian runs on top of a basic Debian Linux system. It is not recommanded at all to do the traditional "apt-get update&apt-get upgrade" commands: this could break your Zynthian system.

You have been warned !!!

If you are using an official Zynthian SD Image, the first thing you should do after booting up your Zynthian Box is update the software.

Updating from the UI

If your Zynthian's UI is working OK and you can control the interface using the knobs or the touch screen, you can update your software very easily:

  1. Connect your Zynthian Box to your router/switch using an Ethernet RJ45 cable. Alternately, you can configure the WIFI connection using the Webconf tool.
  2. Click update software from the UI's Admin Menu
  3. Click restart UI (or reboot) from the UI's Admin Menu
