Jellyfin not starting up after upgrading to 10.9.0

[gingerbreadassassin]

I don't know what to do.. I have tried setting the image version to 10.8.13, but that gave many errors, It seemed that 10.9.0 update have changed a lot of things.

This thread from post #3 and on basically has nothing to do with the OP's problem. I ran into this issue running jellyfin via truecharts and a failed upgrade via heavyscript from 10.8.13 -> 10.9.3. The clue is this line:

Code:

[21:41:36] [INF] Library database backed up to /var/lib/jellyfin/data/library.db.bak40

If you look in the /var/lib/jellyfin/data/ directory, you'll see a bunch of library.db.bak* files, though I believe the corruption (if it really is corrupt and not just a failure in the migration logic or I attempted too great a version jump) is actually in the original library.db. I solved my issue by moving the library.db* files to a backup directory. Jellyfin was then able to start, but it did have to rebuild the library. Mine did this automatically, and was done in less than 5 minutes.

Here's roughly the commands I used:

Code:

$ cd /var/lib/jellyfin/data
$ mkdir librarybak
$ mv library.db* librarybak/

Hope others find this useful.
