On the french forum a staff member said it will be fixed in 9.2.2

Solved, version 20.3.5 is for Kodi 20. You won’t be able to install it on current Kodi (version 19.5).

You need to wait for the devs to update it 🙂

Hi @jarod98
Thanks for your mention 🙂

@olivernoah Thank you for your answer and for your encouragement. You are the only one has answered me and gave a path to resolve my problem. In Batocera forums I've not such luck.
By now I've got working the Realtek RTL2832 DVB device: I've noted that .ko files needed (included module dependencies) I use from another distro with upper kernel release are valid in an environment with a lower kernel release (6.x). In fact this should be fine for TBS device but althought I compile against the Batocera kernel release it cannot load the module due to several issues related with symbols and kernel versions I'll troubleshoot later.
With a problem solved next I do is run NextPVR backend. It does with an specific .NET runtime for Linux and it runs fine and can discover DVB devices but it lacks of many software dependencies like libraries and dtv-tables to fully work. These dependencies could be installed from pacman but it shouldn't be like this (documentation also points this) and it "floods" the entire system with files and libraries that could be not necessary.
I'm searching for more self-contained PVR backend solution.
Of course nothing of these could be possible without the overlay system.
I'm keeping look for ... I think the solution for Batocera will be the same for Recalbox.

Regards.

On new version no problem

On kodi it's possible but somme addons not work.
On the other hand on recalbox everything is frozen impossible to add a core.
Because recalbox is a full-fledged OS, and a lot of library linux does not exist

@stoppedwumm That's going to be very difficult to achieve. Recalbox runs on a very minimal stripped-down Linux with only the very basic tools available. So you can't just install extra software with apt.

You could in theory download the source for OpenVPN and compile it yourself, but you would probably find a lot of dependencies missing.
