@dbkarm:
Please try to start JDownloader manually via
java -jar JDownloader.jar in your JDownloader directory.

Error sounds more some java starting issue. Do you launch within a container that has not enough memory? At least that shows up when googling this error

That's because it was the second time I launched it. This is the first time log. The user interface does not launch.

@dbkarm: Java requires X11 and most likely you don't have X11 emulation installed and Wayland only
Or you use a shell that does not have X11 environment variable set.

@dbkarm: What java package have you installed? How did you install JDownloader?
JDownloader starts in headless mode.
1.) make sure you have installed full java package and not headless one
2.) make sure xwayland is installed/setup
3.) open shell/bash...and check output of

I think I've installed it using the official installer

Code:
java -version
openjdk version "21.0.5" 2024-10-15
OpenJDK Runtime Environment (build 21.0.5+11-Ubuntu-1ubuntu124.10)
OpenJDK 64-Bit Server VM (build 21.0.5+11-Ubuntu-1ubuntu124.10, mixed mode, sharing)
the desktop

Code:
echo $DISPLAY
:0.0
xwayland:

Code:
sudo apt install xwayland
xwayland is already the newest version (2:24.1.2-1ubuntu0.1).

@dbkarm: Thanks for the follow-up. I'm trying to setup a VM with this OS/Desktop combination and checking if I can reproduce the issue

Can you please check what java package (not java -version) you have installed? eg with

Most likely you have a default java headless version
Please do this
Quote:
apt remove *jdk*
Quote:
apt install openjdk-21-jre
I could reproduce this by installing a "-headless" package version as well.
