Okay, so I re-installed max2play another time.
Have let it update itself.
Have installed the vnc server, tried it, found it cannot display the kodi screen, logged off from it, deinstalled it, rebooted.
LMS and squeezelite are running, they show process IDs.
But shairport won’t start up, it tells me:
Trying to launch … NOT successful Click here to show detailed information
startup
couldn’t create avahi client: Daemon not running!
Calling avahi-publish-service failed !
Calling mDNSPublish failed !
Could not establish mDNS advertisement!
Why is that and what else do I need to configure for this „out of the box“ environment?!
