Hey, I’m running the linuxserver/beets container, not changed a thing in years but this error popped up a couple of days ago. I realise the same error has been reported a year or more ago however given nothing has changed on my machine, I suspect there’s something wrong inside the container.

I switched to nightly as per the instructions here: [Update to python 3.8.10 breaks image on Raspberry Pi · Issue #80 · linuxserver/docker-beets · GitHub](https://github.com/linuxserver/docker-beets/issues/80)

I wouldn’t consider this “solved” if it means not using a release tag. Can this get addressed by a new release please @adrian?

@trolley, publishing a new release is a time consuming process. See this discussion: [Forming a beets "core team"](https://discourse.beets.io/t/forming-a-beets-core-team/639)

OK, thanks. I’ll switch to the nightly docker container for now.
