SOLVED: Can't upgrade jellyfin-server due to missing deps

[Lilly]

I had the same issue (only on debian 13.1 and with libicu72 not installable)
I fixed it by updating my jellyfin sources. I edited /etc/apt/sources.list.d/jellyfin.sources to look like this 

Code:

Types: deb
URIs: https://repo.jellyfin.org/debian
Suites: trixie
Components: main
Architectures: amd64
Signed-By: /etc/apt/keyrings/jellyfin.gpg

I had to change Suites from bulseye to trixie.
Hope this helps.

In my circumstances, updating so it is noble for the suites seems to have fixed things!
