I am on Fedora Linux 44 (COSMIC) x86_64. Earlier this week, on Friday, September 4th i clicked Update all in Cosmic Store and some time later I restarted JDownloader2, only to have it never launched again.
When I launch it from the terminal, it only displays some warnings but does not terminate.
m@fedora:~/.jd2$ ./JDownloader2
WARNING: package com.sun.awt not in java.desktop
WARNING: package com.sun.java.swing.plaf.windows not in java.desktop
WARNING: package sun.security.action not in java.base
WARNING: A restricted method in java.lang.System has been called
WARNING: java.lang.System::load has been called by net.sf.sevenzipjbinding.SevenZip in an unnamed module (file:/home/m/.jd2/libs/sevenzipjbinding.jar)
WARNING: Use --enable-native-access=ALL-UNNAMED to avoid a warning for callers in this module
WARNING: Restricted methods will be blocked in a future release unless native access is enabled
At first I thought that my installation is corrupted, so I launched the install script again and here’s something weird: it doesn’t start either but displays an error:
m@fedora:~/Pobrane$ ./JDownloader2Setup_unix_nojre.sh
Starting Installer ...
Could not display the GUI. This application needs access to an X server.

You can also run this application in unattended mode without

I hoped reinstalling Java runtime would solve the issue, as it was the only thing I had to install before JDownloader so i tried sudo dnf reinstall java-latest-openjdk but it didn’t help.
What else can I do?
