Logstash file is missing in /etc/init.d after installing logstash

Elastic Stack Logstash
1

I am installing logstash 6.3.0 in Ubuntu with the following commands

curl -L -O https://artifacts.elastic.co/downloads/logstash/logstash-6.3.0.deb
sudo dpkg -i logstash-6.3.0.deb

Although the installation is completed, Still no logstash file will be created in /etc/init.d directory and therefore having issues in starting logstash

Any ideas what I am doing wrong here ?

seems like the issue is in the deb file. I installed a lower version with the following URL and it creates the file successfully
https://download.elastic.co/logstash/logstash/packages/debian/logstash_2.3.4-1_all.deb

Are there any place to get an .deb file of 6.3 logstash ??

logstash later versions does not create a logstash file within etc/init.d directory.
still the logstash server can be started using another service starting command

"systemctl start logstash"
