Package: nfs-kernel-server
Version: 1:2.8.2-1

Install of nfs-kernel-server hangs before the end. Last messages : nfs-mountd.service is a disable or a static unit, not starting it lfsdcld.service is a disable or statis init, not starting it.

Check was done on a new-installed system, just after the first boot. The problem appears after the changes on iptables;
nfs-kerne-server works whitout any problem on the same machine with others systems installed before the changes of the iptables.
System: Debian trixie installed on 12-26

I believe I can reproduce a problem, and the hang of the installation
is not the root cause, can you confirm you see a kernel splat
something like:

Can you confirm that?
