    Safest way to clean up boot partition - Ubuntu 14.04LTS-x64, Ubuntu 16.04LTS-x64

Reference
Case I: if /boot is not 100% full and apt is working

1. Check the current kernel version

$ uname -r
	public class ReportCpuCount {
	public static void main(String[] args) throws Exception{
	while(true){
	System.out.printf("#Found %d CPUs%n", Runtime.getRuntime().availableProcessors());
	Thread.sleep(1000);
	}
	}
	}
