Problems updating Volumio

I have installed an Oled screen with the antiprism method, it works very well.
But now the update of Volumio refuses to install.

is it due to the installation of the screen?

Can I solve this without having to do a complete reset?

Thanks

I think it is because you have modified the system and have used ssh and therefore you cannot update.

see link and then at the bottom of the page.

Thanks michel8166

As I have nothing to lose I will try the manual update of the backend.
If you know how to do it,
could you tell me how to do it?

Best Regards
Edu
