Sorry! We are trying to improve the development cycle to avoid this kind of errors.
The new ZynthianOS building system, that we are testing right now, will release images every day and will be easy to create development and production images, among others:

It’s fixed now and a software update from the admin menu or command line should be enough.
If still not working, try burning a fresh SD with the last Gorgona Omega image and then update software.
