I'm trying to run Cypress tests on the Hosted Linux Pool for Azure Pipelines. Unfortunately, the Hosted Agent doesn't have all the dependencies for Cypress installed.
Running the documented apt-get doesn't work:

Running apt-get update takes forever (25 minutes and still not done).
Any clues on how to get Cypress working quickly on the Hosted Agent is welcome.
Note: I tried running on Windows, that works, fortunately, so I'm not completely blocked. But to use the Windows Agent I now have 2 agent phases which adds overhead due to artefact downloads and npm install overhead.
