Error: Cannot hard link across devices.link

Hi, I’m running the latest Linuxserver’s docker of Beets on a Synology NAS with both the /downloads and /music on the same partition. When I launch the import command via ssh it show me this at the end:

Hmm; something looks like it went really wrong here! Can you please file a full bug report?
