StarMade is silently failing to launch on Linux
Often, the Linux StarMade Launcher will silently fail to launch for new users. The most common reason for this happening is that StarMade is attempting to use a very out of date Java 7 binary, which does not work on most modern Linux systems. Switching to a newer version of Java (OpenJDK 8, Oracle Java 8) will most likely fix this issue.
Switching to OpenJDK8
Install OpenJDK 8
CentOS / Fedora: sudo dnf install java-1.8.0-openjdk Debian / Ubuntu: sudo apt install openjdk-8-jdk Arch / Manjaro: sudo pacman -S jdk8-openjdk Other distributions may vary, check your distributions docs if not sure
