electron: 5.0.0-beta.1
platform: linux x64

**Actual behavior**

https://github.com/electron/electron-quick-start app fails to start with the following error:
```
[3937:0131/003107.790938:FATAL:zygote_host_impl_linux.cc(116)] No usable sandbox! Update your kernel or see https://chromium.googlesource.com/chromium/src/+/master/docs/linux_suid_sandbox_development.md for more information on developing with the SUID sandbox. If you want to live dangerously and need an immediate workaround, you can try using --no-sandbox.
```

**To Reproduce**

- `git clone https://github.com/electron/electron-quick-start.git`
- `cd electron-quick-start`
- `npm install`
- `npm add --only=dev electron@5.0.0-beta.1`
- any of the following commands fail:
  - `npm start`
  - `node_modules/.bin/electron --version`

**Additional Information**

Worth to mention that event just `node_modules/.bin/electron --version` execution fails with the same error.
