It is a synology NAS and all forum posts and tutorials say to install container managerand set up docker. Well tough luck because my model doesn’t seem to be compatible with container manager.
Ok, I install the the server in a pc running linux mint, now when I try to create a library I can’t point where the files are.
On my DS1522+ I have installed the Jellyfin app from the SynoCommunity repository. I used to have Jellyfin on a separate host, but using the app has been much less painful. Maybe that’s an option for you?
That was my first idea, unfortunately the DS416 does not support the container manager that I read everywhere is necessary to install jellyfin.
You might try it anyway; as far as I know Container Manager is not required for the Jellyfin app. I have several containers running, but not Jellyfin. Jellyfin is just a regular app installed through Package Center (after adding the SynoCommunity repository).
