I have a shared network hard drive that is connected to one of two RPI3s On one RPI3 libreelec 9.2.1 is installed on the other libreelec 9.2.2 Each media center has access to the movie folder. One scan finds all the films, the second only a few. I use The Movie Database. The settings are the same. Internet is available on both devices. But one of the media centers does not add films. I apply logs from the problem device. http://ix.io/2p3B http://ix.io/2p3C Sorry for my English.
Both your log files show a souvenir from video piracy repositories (=superrepo).
