Docker Compose Fails

[SirFfej]

Migrating a Jellyfin server from a windows instance to a Linux server.

I was able to get it to build via Docker Compose image but am now getting an 'Access to the path '/config/config/system.xml' error and am not understanding why after a great deal of trial and error.

Error is below
*******

I did use an updated script to migrate the dta, metadata, config, plugins, and root data from my windows server to the linux server.

Any help would be appreciated.

I had something similar happen to me. Turns out that if /etc/jellyfin (and /mnt/MediaServer/jellyfin) doesn't already exist when you start the container, Docker will create the mount points with root:root owner and group. Make sure that your mount points have the correct owner and permissions, that should help.
