Raspberry Pi Trixie NXFilter autoupdate via script to 4.7.3.9 fails due to JDK dependency

[Potemkin]

Hi,
Raspberry Pi OS 64bit Trixie Kernel

~ $ uname -r
6.12.47+rpt-rpi-v8

JDK 21 installed.

~ $ java -version
openjdk version "21.0.9" 2025-10-21
OpenJDK Runtime Environment (build 21.0.9+10-Debian-1deb13u1)
OpenJDK 64-Bit Server VM (build 21.0.9+10-Debian-1deb13u1, mixed mode, sharing)

Running the NXfilter autoupdate script fails due to JDK dependency issue.

Unsatisfied dependencies:
nxfilter : Depends: openjdk-11-jre-headless but it is not installable or
openjdk-17-jre-headless but it is not installable
Error: Unable to correct problems, you have held broken packages.
Error: The following information from --solver 3.0 may provide additional context:
Unable to satisfy dependencies. Reached two conflicting decisions:
1. nxfilter:arm64=4.7.3.9 is selected as an upgrade
2. nxfilter:arm64=4.7.3.9 Depends openjdk-11-jre-headless | openjdk-17-jre-headless
but none of the choices are installable:
[no choices]

### Starting NxFilter.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Looking at the Jesse repository, only JDK 21 and 25 available.

We will add 21 and 25 then. We will let you know after we add them.

The DEB package has been recompiled. Try it again.

Thank you for your help. That seems to have fixed it.
