Cannot `cypress verify` - Hangs on Smoke Test on WSL2

Current behavior:

I have just installed version 4.4.0 of cypress and integrated it in to my project. I’m using using WSL Ubuntu and have install the suggested packages in the documentation.

After trying several fixes as well as reverting the version to earlier versions where I’m met with different issues.

After running DEBUG=cypress:* yarn run cypress open it looks like it’s getting stuck on the smoke test time out .

  cypress:cli disabling Electron sandbox +57ms
  cypress:cli running smoke test +1ms
  cypress:cli using Cypress executable /home/<user>/.cache/Cypress/4.4.0/Cypress/Cypress +0ms
  cypress:cli smoke test command: /home/<user>/.cache/Cypress/4.4.0/Cypress/Cypress --no-sandbox --smoke-test --ping=47 +0ms
  cypress:cli smoke test timeout 30000 ms +0ms
  ⠼  Verifying Cypress can run /home/<user>/.cache/Cypress/4.4.0/Cypress

Desired behavior:

It should continue to verify and then open Cypress

If anybody could point me in the right direction that would be much appreciated

Versions

Cypress: 4.4.0 Windows 10 Ubuntu 18.04.4 LTS

@timharsch your solution worked for me on WSL2. I had a DISPLAY env variable set for VcXsrv, and after running unset DISPLAY the verification step completed w/o issues.

Same here in WSL2 Ubuntu 20.04 LTS and Cypress 8.0.0

if DISPLAY env variable is set it fails but unsetting the variable by doing so is making it work :

unset DISPLAY
