Hi there, you need JDK 8 from Oracle. Using OpenJDK can crash your installation process: Please check: $ java -version $ javac -version make sure it Oracle java, else you can download Netbean that bundle with JDK here ( http://www.oracle.com/technetwork/java/javase/downloads/jdk-netbeans-jsp-142931.html ) Then for installation, please chmod you installer as executable file first (If you already hava Oracle JDK and want to use existing installer) $ chmod a+x ./netbeans-8.2-linux.sh $ ./netbeans-8.2-linux.sh (if you use Netbean bundled with JDK) $ chmod a+x jdk-8u171-nb-8_2-linux-x64.sh $ ./jdk-8u171-nb-8_2-linux-x64.sh No need to run installer as root, since I saw you run it as root # If you interested to have multiple java / jdk, check my old blog post https://robbinespu.github.io/eng/2018/03/21/Updating_java_with_alternative.html I hope it help you installing netbeans _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
