Ubuntu: Cannot start ChromeHeadless

I’m having some trouble getting ChromeHeadless to start. The error message doesn’t give much information:

Here is my karma config:

            },
            tsconfig: "./tsconfig.json"
        }
    });
};

Any suggestions?

I’m on Ubuntu 16.04 and Chrome 62.

@raveneyex I’ve defined a custom launcher based on ChromiumHeadless. The custom launcher allows flags to be passed to the Chrome (or Chromium) instance.

process.env.CHROMIUM_BIN = require('puppeteer').executablePath();
module.exports = function(config) {
  config.set({

   ....*other karma config settings*....

    browsers: ['HeadlessChromium'],
    customLaunchers: {
      HeadlessChromium: {
        base: 'ChromiumHeadless',
        flags: [
          '--no-sandbox',
          '--remote-debugging-port=9222',
          '--enable-logging',
          '--user-data-dir=./karma-chrome',
          '--v=1',
          '--disable-background-timer-throttling',
          '--disable-renderer-backgrounding',
          '--proxy-bypass-list=*',
          '--proxy-server=\'direct://\''
       ]
      }
    }
  });
};

To make this run successfully, Please follow the procedure

Method 1: Most of the issues will be fixed and we can run ChromeHeadless if we download chromium version(debian) in wsl and install

step 1: install necessary packages

sudo apt-get update

sudo apt-get install -y curl unzip xvfb libxi6 libgconf-2-4

step 2: install chromium

wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb

sudo apt install ./google-chrome-stable_current_amd64.deb

If still problem persists, please follow the method 2

method 2: To run a basic Selenium UI test on any environment we need a browser and a driver to control the browser. So we’ve to make Windows’s Chrome browser and the chromedriver accessible from WSL.

step 1: Link Chrome browser on Windows

sudo ln -sf '/mnt/c/Program Files (x86)/Google/Chrome/Application/chrome.exe' /usr/bin/google-chrome

step 2: Link chromedriver on Windows

sudo ln -s /mnt/c/Users/username/node_modules/chromedriver/lib/chromedriver/chromedriver.exe /usr/bin/chromedriver

step 3: Change CHROME_BIN (environmental variable’s default value)

export CHROME_BIN='/mnt/c/Program Files (x86)/Google/Chrome/Application/chrome.exe'

If still problem persists, please follow the method 3

Method 3: This will help run puppetteer on Ubuntu, so let’s install necessary packages:

sudo apt-get install gconf-service libasound2 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 libgtk-3-0 libnspr4 libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 ca-certificates fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils wget

My StackOverflow solution link

for me it says, [INFO] [0518/130005.862638:ERROR:zygote_host_impl_linux.cc(90)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180.

I’ve done everything also provided different flags from issues but still couldn’t launch chrome headless on Ubuntu 22.04
