I have Kodi 20.5 installed on my Raspberry Pi running Raspberry OS 12.7. That works fine, but I wanted to install the new version 21.1. As there is no package available for the Raspberry Pi, I tried to install form source. This kind of worked, but I got it not really running. Finally I decided to run the old version again.
During the installation of the version 21 some addons were updated, and I am afraid some files in my home directory were modified. When I restarted the version 20, it did some addon updates again, and all seems to work fine. But the radio addon disappeared from the list. When I tried to activate it again, it says it would be incompatible with the API. I activated it regardless, but it does not work anymore.
What can be done to make it work again?
