SOLVED: Playback Error. Playback failed due to a fatal player error.

The prune should have already cleaned up all the temporary data. If you have nothing you want to preserve from the previous instance, we can delete the volumes that you had created.

Code:

sudo docker volume ls

This will list out the remaining volumes. Based on the tutorial you probably called them jellyfin-config and jellyfin-cache

Code:

sudo docker volume inspect jellyfin-config jellyfin-cache

This will show you info about it, including verifying that this is the volume located at /var/lib/docker/volumes. If so...

Code:

sudo docker volume rm jellyfin-config jellyfin-cache

That should finish cleaning up the previous instance.
