I just downloaded package from blogspot page: jdkmon_17.0.18-1_amd64.deb and installed it.

When i run it from launcher nothing happens. When i run it from cmd i get this:

Tried it run manually under JDK17, not working.

petr@probook:/opt/jdkmon/lib/app$ /usr/lib/jvm/jdk-17/bin/java -jar JDKMon-17.0.18.jar

When running the deb, the default Java version doesn't matter because JDKMon comes bundled with it's own JDK. If you use the jar you also need to have JavaFX correctly installed. I run the deb myself on my Linux box on Ubuntu without any problem. Just to make sure you are aware of how it should work...if you start it, it will take some time before the main window will show up. First it will check for installed JDK's and by doing this it will also check JDK's it found for vulnerabilities. The app itself should then show up in the sidebar in Ubuntu. Every 3 hours it will automatically check for updates and will show notifications on the screen in case it found some.

Hmm probably its running, i can see it in processes, but i don't see it on panel. image

Like mentioned in the readme, the system tray icon is only supported on some Linux distributions, unfortunately not on Ubuntu :( I also have it running on a Raspberry Pi 4 with it's 64bit Raspbian and there it shows the icon. Unfortunately this is not under my control and I hope Ubuntu will be supported in the future.

So on my Ubuntu box it appears on the sidebar, not on the system tray

I have Linux Mint with Cinnamon desktop environment, there is no sidebar. Nevemind. Anyway, thank you for your help.
