I would like to bring that request back on the table.
But I don’t request a GUI oder VNC Container here. Jdownloader is capable of running headless. On could use a Jdownloader Instance on a Computer to connect to it or use https://my.jdownloader.org to control it. There is a image I’m aware of doing that: GitHub - jaymoulin/docker-jdownloader: JDownloader 2 Docker Image (Multiarch) - Passed 40M Downloads
However, while this particular image is the best currently available, it’s not working properly in all cases and is not satisfying. Something like this on the linuxserver quality level would be great!
