Fail to install jellyfin

[Xna]

Morning lads,
I was running a jellyfin server under :

Code:

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 24.04.2 LTS
Release:        24.04
Codename:      noble

My server is actually a vm running inside proxmox. Everything was working until a couple of days ago where i notice my vm was still up but jellyfin was not working.
When I checked the status in systemd I found this :

Code:

sudo systemctl status jellyfin.service
× jellyfin.service - Jellyfin Media Server
    Loaded: loaded (/usr/lib/systemd/system/jellyfin.service; enabled; preset: enabled)
    Drop-In: /etc/systemd/system/jellyfin.service.d
            └─jellyfin.service.conf
    Active: failed (Result: core-dump) since Tue 2025-07-08 22:47:53 CEST; 691ms ago
  Duration: 636ms
    Process: 2678 ExecStart=/usr/bin/jellyfin $JELLYFIN_WEB_OPT $JELLYFIN_FFMPEG_OPT $JELLYFIN_SERVICE_OPT $JELLYFIN_NOWEBAPP_OPT $JELLYFIN_ADDITIONAL_OPTS (code=dumped, signal=ABRT)
  Main PID: 2678 (code=dumped, signal=ABRT)
        CPU: 519ms

I was not able to find a way to fix this so I juste uninstall jellyfin using sudo apt remove jellyfin*.
Then I tried to reinstall it using this command : 

curl -s https://repo.jellyfin.org/install-debuntu.sh | sudo bash
But the script fail when it tries to run : apt install --yes jellyfin, telling me it's unable to locate jellyfin package.
So i also tried to install through .deb packages which seem to have worked, because the service is active inside systemd but actually nothing is happening. If i looking into the trafffic of the port i see nothing is going thourhg and i cannot connect it,
Any help welcome
Best regards

It seems I finally managed to solve the issue, for reason I don't get I had a foreign architecture installed with dpkg (arm64) and it seems that apt was seing two architecture and was trying to fetch the wrong one. Here's the ouput of my apt config :
pt-cache policy jellyfin jellyfin-server jellyfin-ffmpeg7 | head -20
jellyfin:

I ran this :
dpkg --print-foreign-architectures
sudo dpkg --remove-architecture arm64
sudo sed -i 's/^Architectures:.*/Architectures: amd64/' \
/etc/apt/sources.list.d/jellyfin.sources
sudo dpkg --purge jellyfin jellyfin-server jellyfin-web \
jellyfin-ffmpeg5 jellyfin-ffmpeg6 jellyfin-ffmpeg7
sudo rm -rf /var/lib/apt/lists/*jellyfin*
sudo apt update
sudo apt install jellyfin-ffmpeg7 jellyfin-server jellyfin-web

And it seems to be fixed now, I'm not sure what caused the issue in the first place

Nice work! Removing the foreign architecture was the perfect fix. I've learned from you.
