  await electron.launch({ args: ["main.js"] });
});

const { app, BrowserWindow } = require("electron");

function createWindow() {
  const mainWindow = new BrowserWindow();
  mainWindow.loadFile("index.html");
}

app.whenReady().then(() => {
  createWindow();
});

Expected behavior

Launch successfully

Actual behavior

Error: Process failed to launch!

Additional context

Following the solution introduced in #11932 (comment) , I am trying to launch Playwright using xvfb-run.
I apologize, as the implementation of Playwright should not be the problem, but I am looking for a new solution.

Playwright's own CI is also seeing this. Most likely related to electron/electron#42510 and GH Actions changes.

See #34238. The ubuntu-latest tag was changed to point to Ubuntu 24.04 and has caused regressions. If you're encountering the same issue then sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0 will fix Electron for you.

Confirmed! Thank you! 😀

- run: sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0
- run: xvfb-run --auto-servernum --server-args="-screen 0 1280x960x24" -- npx playwright test
