Some of the older runtimes are leveraging deprecated Ubuntu versions. How do I understand which OS version is being used by the different runtimes?

We list the OS version in the "Environment" section of each runtime version's release notes. See link to all the runtime release notes here: https://docs.databricks.com/release-notes/runtime/releases.html
