That’s weird. Can you include details about your system? I think beets for some reason believes your filesystem has an extremely short maximum filename length.
Hi thank you for your help, setting max filename lengths fixed it.
My system setup is as follows:
Debian Buster in a VM as guest on a windows server 2016 host. The data folder with music is on the host system and shared with the guest and mounted into the aforementioned folder.
Honestly I only did it this way because I had cryptic terminal output from beets on windows. Setting terminal to UTF didn’t work for me.
