SOLVED: Jellyfin doesn't start after reboot

[Met]

Hi, new to Jellyfin here, trying to install it on an RPi5.

I used the command provided, and setup the libraries, but at some point Jellyfin crashed, and doesnt start again when rebooting the RPi.
I ran the status command to see what was up, but I'm afraid I don't understand any of it. Here's what it gives :

× jellyfin.service - Jellyfin Media Server
    Loaded: loaded (/lib/systemd/system/jellyfin.service; enabled; preset: enabled)
    Drop-In: /etc/systemd/system/jellyfin.service.d

Any help appreciated.

Let me start with RPi5 is not a good platform for Jellyfin.

N100 based is a bit more expensive but MUCH more powerfull.

That being said it should start.

Can you post the output of:
sudo journalctl -u jellyfin -n 200

I had the same problem using Armbian/Ubuntu Noble Numbat arm64.
This was the solution: sudo mkdir /var/log/jellyfin
