Script exited with non-zero exit status: 100.Allowed exit codes are: [0] : packer error

Question

i am trying my hands on packer , i am new to it .

This is my following is the packer code. I chose inline shell because i am not greatly aware of any configure management tool like ansible or chef .

{
    "variables": {
      "aws_access_key": "",
      "aws_secret_key": ""
    },
    "builders": [
      {
        "type": "amazon-ebs",
        "profile":"sumanthdev",
        "region": "me-south-1",
        "source_ami_filter": {
          "filters": {
            "virtualization-type": "hvm",
            "name": "ubuntu/images/*ubuntu-xenial-16.04-amd64-server-*",
            "root-device-type": "ebs"
          },
          "owners": ["099720109477"],
          "most_recent": true
        },
        "instance_type": "t3.micro",
        "ssh_username": "ubuntu",
        "ami_name": "packer-example {{timestamp}}"
      }
    ],
    "provisioners": [
        {
          "type": "shell",
          "inline": [
            "sleep 30",
            "sudo su",
            "apt-get update",
            "apt-get install git -y ",
            "sleep 30",
            "apt-get install nodejs",
            "apt-get install npm",
            "sleep 30",
            "apt-get update",
            "wget https://packages.microsoft.com/config/ubuntu/16.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb",
            "dpkg -i packages-microsoft-prod.deb",
            "apt-get update",
            "apt-get install dotnet-sdk-3.1",
            "sleep 30",
            "apt-get install apache2 -y"
          ]
        }
      ]
  }

I am able to validate the code with no error . i am also sure that my inline script is the one which is causing some errors. this is the complete output with error code .
