I confirmed this issue with Cypress 12.13.0 under Ubuntu 20.04 and Node.js 18.16.0 See repo https://github.com/MikeMcC399/cy-xvfb-test Workflow run [5187602242](https://github.com/MikeMcC399/cy-xvfb-test/actions/runs/5187602242) Edit: Still failing in Cypress 12.16.0

@mschile / @jennifer-shehane The problem seems to come from https://github.com/cypress-io/cypress/blob/develop/packages/server/lib/util/system.js where `obj.release` is undefined. The module itself is unchanged since Dec 2019 and was previously working in Cypress `v10.11.0`. It's...
