After a bit of research I found out, that the Launcher is not working with Java 9+. The solution was to remove the latest version and install java-1.8.0-openjdk. If there is an admin reading this, I would suggest, to add a large note to the download page, that describes the system requirements.

Hi, I downloaded from the official page the Linux version of the launcher. I just installed the latest jdk (java-latest-openjdk-devel) and I have all the available updates installed on my Fedora 30 system. When running the file with the following command (without and with sudo): java -jar TechnicLauncher.jar I get the following java exception: Exception in thread "main" java.awt.HeadlessException at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:204) at java.awt.Window.<init>(Window.java:536) at java.awt.Frame.<init>(Frame.java:420) at java.awt.Frame.<init>(Frame.java:385) at javax.swing.JFrame.<init>(JFrame.java:189) at net.technicpack.ui.controls.DraggableFrame.<init>(DraggableFrame.java:32) at net.technicpack.launcher.ui.InstallerFrame.<init>(InstallerFrame.java:79) at net.technicpack.launcher.LauncherMain.main(LauncherMain.java:167) I hope that this can work, bacause I could not find any better launcher alternatives with automatic modpack install.
