**My code :**
This is my Selenium code:
if (browserName.equalsIgnoreCase("chrome")) {
System.setProperty("webdriver.chrome.driver", "/usr/bin/chromedriver");
ChromeOptions options = new ChromeOptions();
options.addArguments("--verbose");
options.addArguments("--whitelisted-ips=''");
options.addArguments("--disable-extensions");
options.addArguments("--disable-notifications");
options.addArguments("disable-infobars");
options.addArguments("--incognito");
options.addArguments("--disable-gpu");
options.addArguments("--no-sandbox");
options.addArguments("--disable-gpu --disable-software-rasterizer");
options.addArguments("--disable-gpu-sandbox");
options.addArguments("--disable-features=VizDisplayCompositor");
These are options I have tried on chromedriver so far
driver = new ChromeDriver(options); // This line is not being invoked successfully.
------------------------------------------
What I tried so far:
1. I tried firefox browser - which is not launching as well
2. I tried to "chmod 777" files, drivers and folders as per requirement
3. I set up few chrome "options.addArguments" to "disbale GPU" , "headless" and "no sandbox" as per google
4. I looked in VM that if there are already multiple instance opened for Chromedriver via "htop" and other commands to kill the older sessions but I did not see any chrome because it's never been launched

Resources: Maven, Chrome,ChromeDriver, Linux(Debian), Java, Testng, jenkins
Link I followed for basic Linux (Debian) set up : https://stgconsulting.com/running-automated-selenium-tests-from-jenkins-on-linux/
Before solution we have been seeing this below error:
[INFO ] 2019-09-20 09:41:19.341 [main] BaseClass - browserName value is : chrome

[INFO ] 2019-09-20 09:41:23.904 [main] SetUpTest - =========== createAccount Test case is Started.
After solution I am not seeing failure/error and I am able to execute lest on Linux (Debian):
[INFO ] 2019-09-20 08:46:30.675 [main] BaseClass - chrome driver is here

solution steps and information:
(1) You can have latest Chrome Linux Browser on your box
(2) Go here https://chromedriver.chromium.org/downloads and do bruteforce of ChromeDriver versions
(3) I am using Chrome linux 77 (as of now 9/20/2019) and chromedriver 76.0.3809.25 , worked for me
(4) "Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code" - got nothing with firewall
(5) Check your Chmod 777 permission for chromeDriver
It's a BROWSER AND CHROME DRIVER MISMTACH , ALL YOU NEED TO DO IS TO CHECK THE COMPATIBILITY
