Hi!
I’ve been having problems running Chrome on Travis CI. Karma’s build process runs as usual, but when it gets to launching Chrome, I get the following error, despite using the `--no-sandbox` flag:
```auto
[launcher]: Cannot start Chrome
[8522:8522:0828/122456.705758:ERROR:browser_main_loop.cc(1417)] Unable to open X display.
[0828/122456.714616:ERROR:nacl_helper_linux.cc(308)] NaCl helper process running without a sandbox!
Most likely you need to configure your SUID sandbox correctly
```
I’ve tried switching my Linux image from Xenial to Bionic, I’ve added the `--disable-setuid-sandbox`, I’ve even tried running tests via Puppeteer as root user (as per [this comment](https://github.com/puppeteer/puppeteer/issues/5429#issuecomment-592515312)), but nothing seems to work.
This is the [latest build](https://travis-ci.com/github/sendahug/send-hug-frontend/builds/181784914), and here’s [my Karma config](https://github.com/sendahug/send-hug-frontend/blob/ci-setup/karma.conf.js).
When running it on my Mac (macOS 10.15.6), Karma launches Chrome, all tests run, everything works right. It’s only on Travis that I can’t seem to be able to run it at all.
New here so hopefully I added needed 🙂
Thank you in advance for any help!
