@Substring Ok but the Recalbox still does detect that there is an update available, so it does seem to connect to internet. If It can't download by not being able to connect to archive.recalbox.com that's ok I can download the updates manually.

What I really need is for the Kodi installation to be able to connect to the internet, the one coming with Recalbox. You mentioned a solution by @Pepe, do you have a link please ?

you see what is working, i see that there are many bugs left 😉 It will be marked stable when it does run as expected AND the upgrading process from 4.0.x to 4.1 is safe, we can't miss that.
