# X_UPGRADE_REGISTRY_UNREACHABLE

## Means

x upgrade could not read the published versions from npm

## Typical cause

bun pm view failed: no network, a proxy, or a registry that refuses the request. Nothing was written

## Fix

`bun pm view @ultimat3/cli version` — once this answers, re-run: x upgrade --json
