Running KryoFlux GUI (Debian 10)

[fryo]

Hi! Can someone please help me to run the KryoFlux GUI on Debian 10? The quickstart manual says that libusb 1.0.9 is required. Is there any need for action?

Code: Select all

user@debian:~$ apt search libusb-1
Sortierung... Fertig

libusb-1.0-0/stable,now 2:1.0.22-2 amd64  [Installiert,automatisch]

Which Java packages are required to run the GUI? openjdk-11-jdk?

Thx!

I get the same listing with "apt search libusb-1" on debian jessie here and the gui runs fine (using openjdk-7-jdk)! Whats the err message if you start the gui with "java -jar kryoflux-ui.jar."?

I'm new to Debian. What's the best way to install openjdk-7-jdk?

[brightcaster]

There is a difference between the java developement kit (jdk) and the runtime invironment (jre). Unless you want to write your own java aplications a simple "apt install default-jre" should do the job.

If you also want to develope and compile you should ad an "apt install default-jdk".

This will install open jdk 11 which should be fine for the kryflux gui. I guess you installed it manually as it can't find the classes path...

Thanks for your help! Here are the commands I used:

Code: Select all

apt remove openjdk-11-jdk
apt autoremove
apt install default-jre

The java version and the error message is exactly the same as before:

I'm not sure why you're getting that error. It seems that the KryoFlux UI thinks it's running on an older version of Java for some reason (the file it is requesting was moved in later versions of Java, but you're seeing the old location being selected, which is clearly incorrect).

I've tried it on my Mac with the same version of Java, using the AdoptOpenJDK distribution and it works.

Code: Select all

$ java -version
openjdk version "11.0.6" 2020-01-14
OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.6+10)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.6+10, mixed mode)

We'll have to install Debian and see if we can diagnose the problem... In the short term, perhaps you could see if the AdoptOpenJDK version works? If you go to the "Linux RPM and DEB installer packages" section this page you can add an apt repository if you prefer.

It would be good to know if the behaviour is different here, but hopefully it will get you up and running.

[brightcaster]

Could you type "update-alternatives --config java" to see if there are artefacts of previos installations?

David

Code: Select all

root@debian:~# update-alternatives --config java
There is only one alternative in link group java (providing /usr/bin/java): /usr/lib/jvm/java-11-openjdk-amd64/bin/java
Nothing to configure.

I'll test to run Kryoflux from a Debian Live image at the weekend. Perhaps something went wrong when uninstalling openjdk-11-jdk?

After installing AdoptOpenJDK the KryoFlux GUI is finally starting:
