I suspect you might be running an older version of LibreTime vs. the current git master.
We are in the process of switching to python3.
If you can try installing the latest master branch on git and see if you run into the same problem. It seems like the issue might be with the version of liquidsoap and we have some fixes for that but I’m not sure when exactly they were merged.
