We’re going to need to know as a minimum:

• Linux distribution and version
• Jellyfin install method and version
• what you have already tried- not sure where all those flags are coming from

I would also support the comments here recommending that you use docker. There’s only a small number of Linux distributions and versions where a distribution package installation of jellyfin is fully supported, but even then what you need to do varies across each one. All Linux distributions and versions support docker and the process is essentially the same for all of them.

Ok, aside from Android, I’ve yet to see any serious usage of SELinux in the real world and I’ve been working on cloud tech for years. Acknowledged issues such as complexity aside, it’s really just that much less relevant in a modern, single purpose environment such as Docker/kubernetes/cloud functions/etc

Who came up with this ridiculous headline?

What are you basing your ‘guess’ on? IKEA typically design their own products. They already produce Smart home speakers. Why do you suppose that this would be a rebranded product from somebody else?
