No usable version of libssl was found

It should.  AFAICT, the official container has its own version.  I'm assuming you are using the official image since the "OS" reports debian.

Code:

****jellyfin container****
I have no name!@jellyfin:/$ apt list --installed | grep libssl
libssl3/now 3.0.15-1~deb12u1 amd64 [installed,local]
****host OS (ubuntu 24.04)****
chris@rat-trap:~$ apt list --installed | grep libssl
libssl-dev/noble-updates,noble-security,now 3.0.13-0ubuntu3.5 amd64 [installed]

On a plain docker install, there are no variables that I am aware of that would explicitly disable/enable libssl.  Or even on a direct linux install.

So I'm assuming a kubernetes setup doesn't have anything to change/set that either.
