Cannot start Karel the Robot on Fedora

Question

So as stated in the title I want to start Karel the Robot on Fedora, I installed the openjdk package and tried everything I found without any success. I'm sadly a total beginner on Linux in general so please walk me through here if you know what to do.

Error is:

@fedora Downloads]$ java -jar karel.jar
Exception in thread "main" java.lang.UnsatisfiedLinkError: Can't load library: /usr/lib/jvm/java-11-openjdk-11.0.11.0.9-4.fc34.x86_64/lib/libawt_xawt.so

Answer 1

This fedora forum post seems to explain how to fix your issue

Answer 2

Fedora 34 example, with a contemporary version of karel, https://github.com/f7g/karel-release

$ git clone https://github.com/f7g/karel-release.git
$ cd karel-release/
$ java -jar karel.jar     ## The karel GUI opens

No issues with the available jdk versions, openjdk version "1.8.0_292" or openjdk version "11.0.11+9" or openjdk version "16.0.1+9"
