There is a way to update with CvH script but my adjustment to work with emby4
shh into LE and type
Codewget -O /storage/.kodi/addons/service.emby4/bin/emby-update https://od.lk/s/OF8xNjAwNjI1MDdf/emby-update
Reboot and then emby-update from ssh again
Have you seen this before when you quoted ? Reboot and type emby-update
