HA Green updates fail

I have an HA Green. Bought this pre configured HA solution as I do not have any technical training. Installed and works, able to find my way around the user interface and add devices etc. . When I try to update using the built in user interface I get an error. This has been an issue since day one with updates. Tried searching the web using HA green software update issues but have not been able to find anything similar or that I can understand. Any help is very much appreciated.
