Unsupported OS

Error message

Unsupported OS

What it means

Platform guard in self_update: a compile-time cfg! cascade over target_os recognized none of windows, linux, or macos, so the current operating system has no corresponding dx release artifact to download. The input at fault is the host OS, for which the updater cannot construct a release download.
