Cypress verify command failing

See original GitHub issue

Current behavior:

After an apt update of ubuntu 18.04 (yesterday 16/01/2020), the following cypress command return an error. npx cypress verify

It looks like this is your first time using Cypress: 3.8.2

✖ Verifying Cypress can run /root/.cache/Cypress/3.8.2/Cypress → Cypress Version: 3.8.2 Cypress failed to start.

This is usually caused by a missing library or dependency.

The error below should indicate which dependency is missing.

Got the source of the problem, Xvfb is run without -screen so electron dies with:

Calling _exit(1). Core file will not be generated.

If is set fallback this._xvfb_args = options.xvfb_args || [ '-screen', '0', '1024x768x24' ] at @cypress/xvfb it looks like everything works.

I’ve got a docker image before it was broken. If I run the following command

cypress run --config-file ./cypress/cypress.json
Cypress could not verify that this server is running:

  > http://localhost:8080/

you can see cypress starts and correctly waits for something that’s not running. If I do an apt update and apt upgrade with the following output:
