too many redirects

Error message

too many redirects

What it means

A sentinel returned by the HTTP client's CheckRedirect hook in downloadToTemp: the release download URL redirected more than 10 times. It fires on redirect loops (misconfigured release mirrors or GitHub URL weirdness); the client aborts the download.

Solutions

1. Retry later — transient redirect loops on CDN edges resolve themselves
2. Verify the release URL/asset still exists on the releases page
3. If persistent, download manually and replace the binary
