Unable to create network config
Thanks for the report, i have the same issue as yours
Hi guys,
welcome to our community.
Look like something changed on actual jellyfin version and we would need to adjust the way how we install this software. I guess we will provide a fix on next release.
PR up to add a fix DietPi-Software | Jellyfin by Joulinar · Pull Request #5559 · MichaIng/DietPi · GitHub
(Therefore I tried to delay the shutdown of the service right after it has been installed)
can u teach how to do this, so just before the arrival of dietpi v8.6?
Please try:
sudo sed -i '/systemctl stop jellyfin/d' /boot/dietpi/dietpi-software
Then install Jellyfin again.
The code posted by @MichaIng might not gonna work. At least we tested a different solution this evening 
Most probably we will release a beta version of DietPi v8.6 on upcoming weekend. I recommend to wait 2 more days.
Add code sucess
apt-get -y --allow-change-held-packages install jellyfin
8096 - /etc/jellyfin/network.xml edit port
The solution was a bit more complicated than I was hoping but is now included for upcoming DietPi v8.6: DietPi-Software | Jellyfin by Joulinar · Pull Request #5559 · MichaIng/DietPi · GitHub
I am running DietPi v8.6.1 and I still have this issue with Jellyfin. Is there something else I need to do?
Welcome to our community.
You could start sharing the exact issue you have. 
It is the same issue as in the original post – when installing Jellyfin using dietpi-software, I get the exact errors from the bottom two screenshots.
What SBC you are running? Some more information on your system would be helpful.
I am using a Raspberry Pi 4B 8gb. Basically everything I have is the same as the original post besides the DietPi version, which is v8.6.1
Can you share the full installation log? At best copy & paste the raw text from SSH console, if possible.
Only explanation I have is that one of the loops waiting for the config file after service start times out. If that is the case the output of the following command would be helpful as well:
journalctl -u jellyfin
The output from installed Jellyfin looks like this (I have only included the bottom part of the install, everything up top seems to work fine and most of it is just grabbing packages from links):

The output from journalctl -u jellyfin is:

Honestly, some of this output looks like from when I installed Jellyfin. I may have messed some stuff up on my own…
That is a strange file location for a DEB package, probably there is a non-original service in place. Can you show:

A quick note: I tried installing jellyfin on my other Raspberry Pi (also running dietpi) and everything worked perfectly. I have somehow managed to mess something up on the first one, I’m just not sure what I did.
I guess this is a conflicting service. It should be /lib/systemd/system/jellyfin.service
I deleted “/etc/systemd/system/jellyfin.service” and “/lib/systemd/system/jellyfin.service” and that solved the problem. Thanks guys. Sorry for posting my question here. If I had realized I messed it up myself, I wouldn’t have posted here.
Thanks again.
