Error installing Jellyfin via SSH on RaspberryPi5

[BlenderPete]

Hi there,
I'm new to Jellyfin and this forum. So pleas be patient if I ask questions that seem dumb :-)
Also English is not my mother tounge. So my text is using plain English words.
If I run the commands

curl -s https://repo.jellyfin.org/install-debuntu.sh -O && \
curl -s https://repo.jellyfin.org/install-debuntu.sh.sha256sum -O && \
sha256sum -c install-debuntu.sh.sha256sum

as provided on the webpage I get the following result

install-debuntu.sh: OK

So everything seems ok.
If I then run the command

sudo bash install-debuntu.sh

as provided on the webpage as well I get the following result

Found the following details from '/etc/os-release':

If this looks correct, press <Enter> now to continue installing Jellyfin.

The error you are experiencing is unrelated to Jellyfin or Jellyfin's repo, but it does cause apt to halt and stop doing anything.

From what I'm reading around the Internet, OMV's repo going down is not uncommon. Can you try running these commands again?

Code:

sudo apt update
sudo apt install jellyfin

[BlenderPete]

I ran both commands.
First ends with the same error message.
I than ran "sudo apt install jellyfin" and I got no error messages.
But when I try to connect to the IP-Address 192.xxx.xxx.xxx:8096 there will no connection be esatblished.
It returns a time out error.

[TheDreadPirate]

Run these commands.

Code:

sudo ss -tulpn | grep 8096
sudo ufw status verbose

Then share the output of both.

[BlenderPete]

This is the output after the first command:
tcp LISTEN 0 512 0.0.0.0:8096 0.0.0.0:* users("jellyfin",pid=878,fd=489))

This is the output after the second command:
sudo: ufw: command not found

Thanks for your help :-)

[TheDreadPirate]

Hmmm. Does Raspberry Pi OS not have a firewall by default?

When you are trying to access Jellyfin from another device, you are explicitly adding http:// at the beginning? Most browsers will use https:// if you don't specify a protocol

[BlenderPete]

I type "jellyfin.org" and the rest is done by the browser ;-)

[TheDreadPirate]

I mean your server.

http://192.168.1.X:8096 ?

Because your browser may automatically change it to https.

[BlenderPete]

I*m sorry.
You mean like in the first post?
My server wants to connect to http://jellyfin.org.

If I type manualy 'https://repo.jellyfin.org/debian' or copy it from this forum and paste in in my browser this error message appears:

That Wasn't Quite Right
Forbidden (HTTP 403)

Request forbidden by admininstrative rules.

But when I try to connect to the IP-Address 192.xxx.xxx.xxx:8096 there will no connection be esatblished.
It returns a time out error.

This is what I am talking about.
