jellyfin won't launch since 10.9.11 update

[jellyhank]

Hi all,

I've been enjoying Jellyfin for the past month or so, and recently decided to update to 10.9.11. I'm running a baremetal (Intel NUC) Ubuntu to host my Jellyfin. 

When I run jellyfin in the terminal, this is what i get:


hank@jellyfin:~$ jellyfin

Any advice would be appreciated! In typical n00b fashion, I didn't make a back-up, ah well ...

Have you always been starting jellyfin by typing literally "jellyfin"? Jellyfin should be starting as a service.

What is the output of this command.

Code:

sudo systemctl status jellyfin

[jellyhank]

Ah, nope! It's always autostarted. But ever since things got funky, I was curious about what would happen if I wrote jellyfin and if the output of that would be a helpful diagnostic.
I've inputted your command. Here's what it says:


hank@jellyfin:~$ sudo systemctl status jellyfin
× jellyfin.service - Jellyfin Media Server
    Loaded: loaded (/usr/lib/systemd/system/jellyfin.service; enabled; preset: enabled)
    Drop-In: /etc/systemd/system/jellyfin.service.d

Running "jellyfin" does not work the same as starting the service. It will use different parameters and not use your existing config files.

Share the output of this command via pastebin.

Code:

sudo journalctl -u jellyfin -n 200 --no-pager

[jellyhank]

I see, thank you!
Here is the output of your suggested command:
https://pastebin.com/amepScL0

[TheDreadPirate]

Try removing /etc/jellyfin/migrations.xml then sudo systemctl restart jellyfin. If it still fails remove all of the XMLs in /etc/jellyfin.

[jellyhank]

Thanks! So I tried deleting migrations.xml and that didn't work, so then I tried deleting all the XMLs in the /etc/jellyfin. No dice. Whenever I try to log into Jellyfin on Chrome, it just says the site can't be reached. What else should I try?

[TheDreadPirate]

Is the service actually running now? If so, clear your browser cache or ctrl+f5.

[jellyhank]

Nah, the service still isn't running. This is what I get with the sudo systemctl status jellyfin command you suggested earlier:

hank@jellyfin:~$ sudo systemctl status jellyfin

Can share the latest output of this command?

Code:

sudo systemctl restart jellyfin

When this fails

Code:

sudo journalctl -u jellyfin -n 200 --no-pager
