    Ok, thx for the input. So last step that actually was quite easy and I did not have to do anything except install the "libjssc-java" deb package that was already in the repository and then copy /usr/share/java/jssc-2.8.0.jar to the /opt/mango/lib dir. Which will replace the default mango jar file and this solved the issue. I did not have to repack or anything else. The replacement jar references a library in the /usr/lib/jni directory that is compiled for the ARM64 architecture.

    SOLVED

    Thanks for the help as always, and now you also know how to fix this going forward.

    Right, so I have one better, there is already a compiled deb package "libjssc-java" that has all the files I believe I need. I have not done it yet, but I suspect I could repack the /opt/mango/lib/jssc-2.8.0.jar with the necessary compiled files. However, I have some questions.

    1. I have no plans on using any serial ports at all, can mango be configured to just ignore all serial ports and associated software?
    2. Do you think there will be any other hardware layer library issues with Mango?

    Thanks as always for your help.

    Phil,

    Thanks for pointing out the serial port issue. I tried deleting the dir you mentioned and reboot with no luck, but upon searching the error "jssc.SerialNativeInterface.openPort(Ljava/lang/String;Z)J" on the almighty infinitely wise web, I found a specific issue for ARM64 and jssc libraries. Mango does not seem to support the jssc libs that ARM64 uses. I have not worked out all the details yet, but here is the thread that describes a similar issue.

    https://github.com/winder/Universal-G-Code-Sender/issues/524

    Since the Pine Rock64 is ARM64 architecture, this seems to be the issue. The solution seems to be tracking down the proper libs and inserting them into the proper areas, which I have not done yet.

    Hey Phil,

    Great, thx for the suggestion. I will try that and report back. Just so you know, I have installed and reinstalled, even fresh installed a Mango 3.4.2 version that I had used prior. Both exhibited the same issue, so the Hardware link to the serial could be significant as this is a brand new hardware platform that I am using. I also have started it under a no console user for security, but wiped everything because of the issue and installed and ran software as root to remove the user factor from troubleshooting.

    Specifically it is a Pine Rock64 with 4GB of Memory. It never occurred to me that the hardware could be an issue as I have loaded this on many different types of hardware and OS, all for testing or Demo purposes. For this specific load, I am planning to use it as an Energy Monitoring system for my house and I settled on this board.

    oops don't want to muddy the water, I have loaded it on a Debian system before, which I am not sure if that was 8 or 9 and it worked perfectly and easily. This particular install is Debian 9 that I am having trouble with.

    It's definitely strange. I have loaded Mango on many platforms before, but I am not sure I ever loaded it on a Debian 9 system. Maybe it was Debian 8. It really shouldn't matter as it is only using Java in any case. Mango is always easy to load and get working, so I am a bit stumped on this one. This is the first time I was not up and running within minutes.

    I am having an issue where the new/edit data source forms do not load and give the error in the title. I have done much testing already, but not all is pertinent. Let me know if you need more info.

    What could cause this issue?
