How do I update on Linux?

The Jellyfin server flatpak is unofficial and was not created by the Jellyfin Project and is not supported.  If you want to upgrade you will have to use a different install method.  Either docker or a DEB package install.  I'm not sure where the flatpak version saves Jellyfin data, but if it isn't in the same locations as a DEB package install you will need to start over.

Thanks for that info. I don't have Docker. So, with the deb package, it says it's installed. But my localhost for Jellyfin still shows 10.8, even though I uninstalled that version from the Pop_OS store.

In Terminal, I even get: "jellyfin-server is already the newest version (10.9.9+ubu2004)."
