Today I tried to update Moonlight-QT from veldenb to the current version under LibreElec 11.0.3, but I always get an abort with an error message. A new installation did not help either. What am I doing wrong? Docker is up to date and running.
I'd guess they broke support for detecting LibreELEC as the add-on is trying to "apt-get" packages in the background, i.e. thinks it's running on a Debian based distro like Ubuntu, and that doesn't work on LE. You need to post the issue on their GitHub issue tracker.
