[BUG] Missing dependencies in Ubuntu 18.04 ( Bionic )

Missing dependencies in Ubuntu 18.04 ( Bionic )

Running playwright tests ( both local and remote ) on Ubuntu Bionic ( 18.04 ), fails due to dependency issues. Even on using the command sudo npx playwright install-deps, the issue remains. However the same code below will work for Ubuntu 20 ( Focal ).

• Playwright Version: [1.19.2, 1.20.0-alpha-mar-8-2022]
• Operating System: [Linux]
• Node.js version: [16.14]
• Browser: [Firefox]

System:

• OS: Linux 5.4 Ubuntu 18.04.6 LTS (Bionic Beaver)
• Memory: 578.48 MB / 912.27 MB
• Container: Yes

Binaries:

• Node: 16.14.0 - /usr/bin/node
• npm: 8.3.1 - /usr/bin/npm

Languages:

• Bash: 4.4.20 - /bin/bash

Code Snippet

• npm i playwright@1.19.2
• Run a firefox server

// index.js

const { firefox } = require("playwright");

(async () => {
  const browserServer = await firefox.launchServer({ port: 8000, wsPath: "ws" });
  console.log(browserServer.wsEndpoint());
})();

Run the above server using node index.js, we get the following error

/home/azureuser/node_modules/playwright-core/lib/utils/dependencies.js:206
    throw new Error('\n' + utils.wrapInASCIIBox([`Host system is missing a few dependencies to run browsers.`, `Please install them with the following command:`, ``, `    ${maybeSudo}${(0, _registry.buildPlaywrightCLICommand)(sdkLanguage, 'install-deps')}`, ``, `<3 Playwright Team`].join('\n'), 1));
          ^

Even on running sudo npx playwright install-deps, the issue remains.

• Running playwright tests on firefox

// sample.spec.ts

import { test, expect } from '@playwright/test';

test('basic test', async ({ page }) => {
  await page.goto('https://playwright.dev/');
  const title = page.locator('.navbar__inner .navbar__title');
  await expect(title).toHaveText('Playwright');
});

// playwright.config.ts

import { PlaywrightTestConfig, devices } from '@playwright/test';

const config: PlaywrightTestConfig = {
  projects: [
    {
      name: 'firefox',
      use: { ...devices['Desktop Firefox'] },
    },
  ],
};
export default config;

Run the test using npx playwright test, we get the following error

Installing libxtst6 fixes the issue

[yury-s]

I managed to reproduce it in Docker, the problem is that libxtst6 is missing. Can you run apt install libxtst6 and see if it helps?

I will prepare a fix.
