Puppeteer is failing to launch the browser in local - node.js

Question

I am getting this error again and again while launching the application. I would have reinstalled puppeteer for like 8-9 times and even downloaded all the dependencies listed in the Troubleshooting link.
Error: Failed to launch the browser process! spawn /home/......./NodeJs/Scraping/code3/node_modules/puppeteer/.local-chromium/linux-756035/chrome-linux/chrome ENOENT
TROUBLESHOOTING: https://github.com/puppeteer/puppeteer/blob/main/docs/troubleshooting.md
This Code is just for taking a screenshot of google.com
NodeJs Version- 14.0.0
Puppeteer Version- 4.0.1
Ubuntu Version- 20.04
I am using puppeteer which is bundled with Chromium
const chalk = require("chalk");
// MY OCD of colorful console.logs for debugging... IT HELPS
const error = chalk.bold.red;
const success = chalk.keyword("green");
(async () => {
try {
// open the headless browser
var browser = await puppeteer.launch({ headless: false });
// open a new page
var page = await browser.newPage();
// enter url in page
await page.goto(`https://www.google.com/`);
// Google Say Cheese!!
await page.screenshot({ path: "example.png" });
await browser.close();
console.log(success("Browser Closed"));
} catch (err) {
// Catch and display errors
console.log(error(err));
await browser.close();
console.log(error("Browser Closed"));
}
})(); ```

As you said puppeteer 2.x.x works for you perfectly but 4.x.x doesn't: it seems to be a linux dependency issue which occurs more since puppeteer 3.x.x (usually libgbm1 is the culprit).
If you are not sure where is your chrome executable located first run:
whereis chrome
(e.g.: /usr/bin/chrome)
Then to find your missing dependencies run:
ldd /usr/bin/chrome | grep not
sudo apt-get install the listed dependencies.
After this happened you are able to do a clean npm install on your project with the latest puppeteer aas well (as of today it will be 5.0.0).
