The same error for me, It is not related to the OS apparently

I found out what was the problem. Apparently you should do the following 1- change the name of the example ( no idea why but if you keep the name the simulation will give you the same output no matter what) 2- go to the method (createContainerCloudletList) 3- the main problem is the path extraction in this line String inputFolderName = ContainerCloudSimExample1.class.getClassLoader().getResource("workload/planetlab").getPath();

since there is a jar file in the path this line gives, it keeps getting null indicating no folder is there, so what i did is I extracted the jar file named cloudsim-examples-4.0.jar, and just put my path written like this String inputFolderName = "/home/alex/Documents/JarsforCloudsim/Cloudsim/cloudsim-examples-4.0/workload/planetlab"; and that fixed the problem
