Practically every installation with the agent-based installer involves a bunch of WARNING-level log messages saying

level=warning msg=Host worker-0 validation: Host couldn't synchronize with any NTP server

Often the validation failures are later resolved.

This process is visible in pretty much any CI run.

I suspect this is just a timing thing - we check the validations straight away and until the NTP sync is complete the validation reports that it is failed. This could possibly be improved by reporting the status as incomplete until we have a result back from at least one attempted sync.

The false positives are confusing for users and train them to ignore real validation failures.
