error resolving channel %q: %v

Error message

error resolving channel %q: %v

What it means

kops.ResolveChannel failed to resolve the cluster's spec.channel — the channel reference (URL or channels:// path) is malformed, unreachable, or the channel document itself is invalid, so no base URL can be established for package manifests.

Solutions

1. Fix spec.channel to a valid channels URL (e.g. https://kops.sigs.k8s.io/releases/stable.txt)
2. Check network access / proxy settings if the channel URL cannot be fetched
3. Pin a specific channel version if the latest channel document is broken
